| 1 | Fe_(2)TiO_(5)nanochains as anode for high-performance lithium-ion capacitor显示文摘The unique crystal structure and multiple redox couples of iron titanate(Fe_(2)TiO_(5)) provide it a high theoretical capacity and good cycling stability when used as an electrode. In this study, the electrospinning method is employed to synthesize one-dimensional(1 D) Fe_(2)TiO_(5) nanochains. The as-prepared Fe_(2)TiO_(5) nanochains exhibited superior specific capacity(500 mAh·g^(-1) at 0.10 A·g^(-1)),excellent rate performance(180 mAh·g^(-1) at 5.00 A·g^(-1)),and good cycling stability(retaining 100% of the initial specific capacity at a current density of 1.00 A·g^(-1) after1000 cycles). The as-assembled Fe_(2)TiO_(5)/SCCB lithiumion capacitor(LIC) also delivered a competitive energy density(137.8 Wh·kg^(-1))andpowerdensity(11,250 W·kg^(-1)). This study proves that the as-fabricated1 D Fe_(2)TiO_(5) nanochains are promising anode materials for high-performance LICs. | Rong Kang Wang-Qin Zhu Sheng Li Bo-Bo Zou Liao-Liao Wang Guo-Chun Li Xian-Hu Liu Dickon H.L.Ng Jing-Xia Qiu Yan Zhao Fen Qiao Jia-Biao Lian | 2021 | Rare Metals2021，40，9： | 3 |
| 2 | Mesoporous silica anchored on reduced graphene oxide nanocomposite as anode for superior lithium-ion capacitor显示文摘Mesoporous silica(mSiO_(2))has attracted great interest as anode for lithium-ion batteries.However,the low intrinsic conductivity is a major challenge for its commercialization.In this study,a low-cost sol–gel method is employed to synthesize mesoporous silica anchored on graphene nanosheets(rGO)for lithium storage.The results exhibit that the nanocomposite(mSiO_(2)@rGO)with high surface area(616.45 m^(2)·g^(–1))has chemical coupling bonds(Si–O–C)between SiO2 and rGO species,which would be favorable for lithium storage upon synergistic effects.Consequently,the mSiO_(2)@rGO exhibits a high specific capacity of 1119.6 mAh·g^(–1)at 0.1 A·g^(–1)with outstanding cycling stability(92.5%retention over 1400 cycles at 1.0 A·g^(–1)). | Sherif A.El-Khodary Gokila Subburam Bo-Bo Zou Juan Wang Jing-Xia Qiu Xian-Hu Liu Dickon H.L.Ng Shuang Wang Jia-Biao Lian | 2022 | Rare Metals2022，41，2： | 3 |
| 3 | LiFePO_(4)and LiMn_(2)O_(4)nanocomposite coating of LiNi_(0.815)Co_(0.15)Al_(0.035)O_(2)cathode material for high-performance lithium-ion battery显示文摘To solve the multiple problems of low ionic conductivity,fast capacity decay,and poor cycling performance of Nirich layered cathode materials,LiNi_(0.815)Co_(0.15)Al_(0.035)O_(2)@LiFePO_(4)@LiMn_(2)O_(4)(NCA@LFP@LMO,abbreviated as AFM)series cathode materials with different coating ratios were synthesized by a two-step ball milling method and precise control of the mass coating ratio of LFP and LMO.The cathode material of NCA,LFP and LMO with a mass ratio of 8:1:1(A_(8)F_(1)M_(1))presents a more desirable nanocomposite coating and still can deliver a discharge capacity of 151.67 mAh·g^(-1)(with a 94.52%capacity retention)after 200 cycles at 1.0 C.Furthermore. | Zi-Wei Lan Jian-Ru Zhang Yuan-Yuan Li Ru-Heng Xi Yong-Xiang Yuan Lei Zhao Xiao-Yi Hou Jia-Tai Wang Dickon H.L.Ng Cai-Hong Zhang | 2022 | Rare Metals2022，41，8： | 1 |
| 4 | Three-dimensional biogenic C-doped Bi_2MoO_6/In_2O_3-ZnO Z-scheme heterojunctions derived from a layered precursor显示文摘Novel 3D biogenic C-doped Bi_2 MoO_6/In_2O_3-ZnO Z-scheme heterojunctions were synthesized for the first time, using cotton fiber as template. The as-prepared samples showed excellent adsorption and photodegradation performance toward the hazardous antibiotic doxycycline under simulated sunlight irradiation. The morphology, phase composition and in situ carbon doping could be precisely controlled by adjusting processing parameters. The carbon doping in Bi_2 MoO_6/In_2O_3-ZnO was derived from the cotton template, and the carbon content could be varied in the range 0.9–4.4 wt.% via controlling the heat treatment temperature. The sample with Bi_2 MoO_6/In_2O_3-ZnO molar ratio of 1:2 and carbon content of1.1 wt.% exhibited the highest photocatalytic activity toward doxycycline degradation,which was 3.6 and 4.3 times higher than those of pure Bi_2 MoO_6 and Zn In Al-CLDH(calcined layered double hydroxides), respectively. It is believed that the Z-scheme heterojunction with C-doping, the 3D hierarchically micro–meso–macro porous structure, as well as the high adsorption capacity, contributed significantly to the enhanced photocatalytic activity. | Hongyan Li Jia Li Ping Yang Dickon H.L.Ng Xinling Cui Fei Ji | 2019 | Journal of Environmental Sciences2019，31，5： | 1 |
| 5 | Nitrogen-doped porous carbon nanofoams with enhanced electrochemical kinetics for superior sodium-ion capacitor显示文摘Many electrochemical energy storage devices,such as batteries,supercapacitors,and metal ion capacitors,rely on effective and inexpensive electrode materials.Herein,we have developed highly active nitrogen-doped porous carbon nanofoams(NPCNs-600-N)for sodium-ion capacitors(SICs).NPCNs-600-N have a highly porous framework,extended interlayer spacing(0.41 nm),and lots of surface functional groups.Accordingly,NPCNs-600-N achieves a high reversible capacity(301 mAh·g^(-1)at 0.05 A·g^(-1)),superior rate capability(112 mAh·g^(-1)at 5.00 A·g^(-1)),and ultra-stable cyclability.The excellent rate and cycling performance originate from the abundant active sites and porous architecture of NPCNs-600-N.Further-more,SICs device is constructed by employing the NPCNs-600-N as the battery-like anode and commercial superconductive carbon black as the capacitive cathode,which delivers high energy/power densities of 92 Wh·kg^(-1)/15984 W·kg^(-1)with a remarkable cyclability(93%reten-tion over 5000 cycles at 1.00 A·g^(-1)).The methodology of the work enables the simultaneous tuning of the porous architectures and surface function groups of carbon for high-performance SICs. | K.Ramachandran Gokila Subburam Xian-Hu Liu Ming-Gang Huang Chun Xu Dickon H.L.Ng Ying-Xue Cui Guo-Chun Li Jing-Xia Qiu Chuan Wang Jia-Biao Lian | 2022 | Rare Metals2022，41，7： | 0 |
