| 1 | Highly active and stable Co nanoparticles embedded in nitrogen-doped mesoporous carbon nanofibers for aqueous-phase levulinic acid hydrogenation显示文摘Developing a highly active and durable non-noble metal catalyst for aqueous-phase levulinic acid(LA)hydrogenation to g-valerolactone(GVL)is an appealing yet challenging task.Herein,we report well-dispersed Co nanoparticles(NPs)embedded in nitrogen-doped mesoporous carbon nanofibers as an efficient catalyst for aqueous-phase LA hydrogenation to GVL.The Co zeolitic imidazolate framework(ZIF-67)nanocrystals were anchored on the sodium dodecyl sulfate modified wipe fiber(WF-S),yielding one-dimensional(1-D)structured composite(ZIF-67/WF-S).Subsequently,Co NPs were uniformly embedded in nitrogen-doped mesoporous carbon nanofibers(Co^(R)NC/SMCNF)through a pyrolysis-reduction strategy using ZIF-67/WF-S as the precursor.Benefiting from introducing modified wipe fiber WF-S to enhance the dispersion of Co NPs,and Co^(0) with Co-N_xdual active sites,the resulting Co^(R)NC/SMCNF catalyst shows brilliant catalytic activity(206 h^(-1) turnover frequency).Additionally,the strong metal-support interactions greatly inhibited the Co NPs from aggregation and leaching from the mesoporous carbon nanofibers,and thus increasing the reusability of the Co^(R)NC/SMCNF catalyst(reusable nine times without notable activity loss). | Shuai Shao Ying Yang Shangwei Guo Shijie Hao Feng Yang Suoying Zhang Yang Ren Yangchuan Ke | 2021 | Green Energy & Environment2021，6，4： | 1 |

| 3 | Chemo-Biocascade Reactions Enabled by Metal-Organic Framework Micro-Nanoreactor显示文摘The one-pot combination of biocatalytic and chemocatalytic reactions represents an economically and ecologically attractive concept in the emerging cascade processes for manufacturing.The mutual incompatibility of biocatalysis and chemocatalysis,however,usually causes the deactivation of catalysts,the mismatching of reaction dynamic,and further challenges their integration into concurrent chemo-biocascades.Herein,we have developed a convenient strategy to construct versatile functional metal-organic framework micro-nanoreactors(MOF-MNRs),which can realize not only the encapsulation and protection of biocatalysts but also the controllable transmission of substances and the mutual communication of the incompatible chemo-biosystems.Importantly,the MOFs serving as the shell of MNRs have the capability of enriching the chemocatalysts on the surface and improving the activity of the chemocatalysts to sufficiently match the optimum aqueous reaction system of biocatalysts,which greatly increase the efficiency in the combined concurrent chemo-biocatalysis.Such strategy of constructing MOF-MNRs provides a unique platform for connecting the“two worlds”of chemocatalysis and biocatalysis. | Jing Zhang Yu Shen Na Jin Xiaopeng Zhao Hongfeng Li Ning Ji Yingjie Li Baoli Zha Lin Li Xikuang Yao Suoying Zhang Fengwei Huo Weina Zhang | 2023 | Research2023，，1： | 0 |
| 4 | CO_(2) coordination-driven top-down synthesis of a 2D non-layered metal-organic framework显示文摘Combining the physical advantages of two-dimensional(2D)inorganic nanosheets and the modular design and programmed structure of metal-organic frameworks(MOFs),2D MOFs remain at the forefront of functional material research.Despite tremendous efforts,precise control in the synthesis of 2D nonlayered MOFs with predesigned topology for desired applications remains challenging.Success in the bottom-up synthesis of 2D nonlayered MOFs via ligand exchange motivated us to incorporate partial BTC(BTC=1,3,5-benzenetricarboxylate)ligand dissociation and CO_(2) capped coordination into the top-down treatment of bulk Cu-BTC MOF,leading to successful conversion of a 3D nonlayered network to a 2D Cu-based topological structure.Notably,a supercritical CO_(2)-containing solvent mixture is employed to provide the desired defect and coordination engineering.Thus,our work introduces a new top-down concept based on modulated synthesis to fabricate high-quality 2D nonlayered MOFs for the first time. | Yannan Zhou Pengfei Yan Suoying Zhang Yunxiao Zhang Hongwei Chang Xiaoli Zheng Jingyun Jiang Qun Xu | 2022 | Fundamental Research2022，2，5： | 0 |
| 5 | Evaporative Cooling Applied in Thermal Power Plants:A Review of the State-ofthe-Art and Typical Case Studies显示文摘A review is conducted about the application of the evaporative cooling technology in thermal power plants.Different case studies are considered,namely,evaporative air conditioners,evaporative cooling in direct air-cooled systems,gas turbine inlet cooling,wet cooling towers,and hybrid cooling towers with a crosswind effect.Some effort is provided to describe the advantages related to direct evaporative cooling when it is applied in thermal power plants and illustrate the research gaps,which have not been filled yet.In particular,typical case studies are intentionally used to compare the cooling performances when direct evaporative cooling is implemented in different types of cooling towers,including the natural draft wet cooling tower(NDWCT)and the pre-cooled natural draft dry cooling tower(NDDCT).It is shown that the NDWCT provides the best cooling performance in terms of power station cooling,followed by the pre-cooled NDDCT,and the NDDCT;moreover,the evaporative pre-cooling is able to enhance the cooling performance of NDDCT.Besides,on a yearly basis,better NDDCT cooling performances can be obtained by means of a spray-based pre-cooling approach with respect to wet media pre-cooling.Therefore,the use of nozzle spray is suggested for improvement in the performance of indirect/direct air-cooling systems with controlled water consumption. | Tiantian Liu Huimin Pang Suoying He Bin Zhao Zhiyu Zhang Jucheng Wang Zhilan Liu Xiang Huang Yuetao Shi Ming Gao | 2023 | Fluid Dynamics & Materials Processing2023，19，9： | 0 |
| 6 | Spray Effect on the Thermal Performances of a Dry Cooling Tower显示文摘Pre-cooling the inlet air of a dry cooling tower by means of a spray can improve the tower performance during periods of high temperature.To study the spray effect on the thermal performance of natural draft dry cooling towers(NDDCTs),in this study 3-D numerical simulations of such a process have been conducted using Fluent 16.2(a two-way coupled Eulerian-Lagrangian approach).The considered NDDCT is 120 m high and only half system is simulated due to its structural symmetry.Three different spray strategies have been investigated at a typical crosswind speed of 4 m/s,which is the most frequent wind speed.The results have shown that:(1)The three implemented spray strategies can improve the thermal performance of the studied NDDCT with a vary-ing degree of success.In one case,the heat rejection rate can be increased by 35.2%,and the tower outlet water temperature can be decreased by 2.1℃ when compared with the no spray case;(2)To improve the thermal per-formance of the NDDCT using a small amount of water,the design of the spray pre-cooling system must include more nozzles on the windward and fewer or even no nozzles on the leeward sides of the NDDCT. | Zhe Geng Feng Feng Shuzhen Zhang Jie Li Chengwei Liu Yang Li Tiantian Liu Suoying He | 2023 | Fluid Dynamics & Materials Processing2023，19，9： | 0 |

| 8 | Synergistic Catalysis of Enzymes and Biomimetic MOFs: Immobilizing Cyt c on Two-dimensional MOFs to Enhance the Performance of Peroxidase显示文摘Metal-organic frameworks(MOFs) have been widely regarded as promising carriers for enzyme immobilization owing to their advantages in improving loading and regulating interaction with enzymes. However, they are still suffering from the problems of slow mass transfer and compromising activity. In this paper, the active two-dimensional(2D) MOF of Cu-TCPP(Fe)[TCPP=tetrakis(4-carboxy-phenyl)porphyrin], which possesses the biomimetic architecture of peroxidase, was adopted to anchor cytochrome(Cyt c) for the enhancement of catalytic activity. The atomic/nanometer thickness and micrometer lateral dimension of 2D MOFs can ensure the full exposure of immobilized enzymes and a shorter diffusion distance for the reactant molecules. Besides, the active carrier can provide synergistic catalysis and activity compensation during the reaction. When tested in the decomposition reaction of H_(2)O_(2), Cyt c/Cu-TCPP(Fe) exhibited nearly twice catalytic activity and an accelerated catalytic rate compared to free Cyt c. | WANG Yitong MENG Fanchen SU Ruifa SUN Changrui HAN Qianqian ZHANG Weina ZHANG Suoying | 2022 | Chemical Research in Chinese Universities2022，38，6： | 0 |
| 9 | Incorporating metal nanoparticles in porous materials via selective heating effect using microwave显示文摘Metal nanoparticle@porous material composites have attracted increasing attention due to their excellent synergistic catalytic performance.However,it is a challenge to introduce metal nanoparticles into cavities of porous materials without agglomeration on the exterior.Despite the progress achieved,a universal approach that can integrate different kinds of metal nanoparticles and porous materials is still highly desirable.Here we report a facile and general approach to fabricating metal nanoparticle@porous materials by microwave-triggered selective heating.The microwave can pass through the non-polar solvent and act on the polar solvent in the porous materials,causing the polar solvent to be heated,vaporized,and away from the pores of porous materials.The local void produced by the escape of polar solvent facilitates non-polar solvent containing metallic precursor to be dragged into the narrow pores,followed by further reduction,resulting in the complete encapsulation of nanoparticles.A series of metal nanoparticles@porous materials,ranging from metal-organic frameworks(MOFs)to zeolites,are successfully prepared by this method and show excellent size selectivity in catalytic reactions. | Yingyu Zhou Jiacheng Liu Fuyuan Sun Junchen Ouyang Ruifa Su Fanchen Meng Yongqi Luo Cheng Xu Weina Zhang Suoying Zhang Fengwei Huo | 2024 | Nano Research2024，17，4： | 0 |

| 11 | Experimental Study on the Resistance and Splash Performances of Water Collecting Devices for Mechanical Draft Cooling Towers显示文摘In recent years,water collecting systems,with the associated advantages of energy saving and noise reduction,have become the foundation for the development of a scheme to optimize the structure of cooling towers.To explore the feasibility of this approach for mechanical draft cooling towers,a small-scale experimental device has been built to study the resistance and splash performances of three U-type water collecting devices(WCDs)for different water flow rates and wind speeds.The experimental results show that within the considered ranges of wind speed and water flow rate,the pressure drop of the different WCDs can vary significantly.The resistance and local splash performances can also be remarkably different.Some recommendations about the most suitable system are provided.Moreover,a regression analysis of the experimental data is conducted,and the resulting fitting formulas for resistance and splash performance of WCD are reported. | Guoqing Long Guogang Zhang Qi Zhang Cuilin Zhao Suoying He Fengzhong Sun | 2023 | Fluid Dynamics & Materials Processing2023，19，7： | 0 |
