| 1 | 一维/二维W_(18)O_(49)/多孔g-C_(3)N_(4)梯形异质结构建及其光催化析氢性能研究显示文摘提高光催化分解水制氢的效率是能量转换领域的关键挑战。本研究首先合成了二维多孔氮化碳(PCN),然后在二维PCN上原位生长了一维W_(18)O_(49)(WO),形成了一种新型的梯形(S型)异质结。该异质结可以加快界面电荷的分离和转移,赋予WO/PCN体系更好的氧化还原能力。此外,具有多孔结构的PCN提供了更多的催化活性位点。与WO和PCN相比,20%WO/PCN复合材料具有更高的H_(2)产率(1700μmol∙g^(−1)∙h^(−1)),是PCN(30μmol∙g^(−1)∙h^(−1))的56倍。本研究提供了一种新S型光催化剂用于光催化制氢领域。 | 黄悦 梅飞飞 张金锋 代凯 Graham Dawson | 2022 | 物理化学学报2022，38，7： | 11 |

| 15 | In-situ fabrication of Bi_(2)S_(3)/BiVO_(4)/Mn_(0.5)Cd_(0.5)S-DETA ternary S-scheme heterostructure with effective interface charge separation and CO_(2) reduction performance显示文摘Exploring new and efficient photocatalysts to boost photocatalytic CO_(2) reduction is of critical importance for solar-to-fuel conversion.In this study,through the in-situ growth method,a series of S-scheme mechanism Bi_(2)S_(3)/BiVO_(4)/Mn_(0.5)Cd_(0.5)S-DETA nanocomposites with good photocatalytic activity were synthesized.The extremely small size of Mn_(0.5)Cd_(0.5)S-DETA nanoparticles provides more active sites for photocatalytic reactions.In order to solve the serious shortcomings of sulfide photo-corrosion,BiVO_(4) were introduced as oxidation catalyst to consume too many holes and improve the stability of the material.In addition,the in-situ growth method produces the reduction cocatalyst Bi_(2)S_(3) during the BiVO_(4) and Mn_(0.5)Cd_(0.5)S-DETA recombination process,thereby improving the efficiency of charge transfer at their interface contact.The ternary composite unveils a higher CO_(2)-reduction rate(44.74μmol g^(−1) h^(−1))comparing with pristine BiVO_(4)(14.11μmol g^(−1) h^(−1)).The enhanced photocatalytic CO_(2) reduction performance is due to the special interface structure of the S-scheme Bi_(2)S_(3)/BiVO_(4)/Mn_(0.5)Cd_(0.5)S-DETA photocatalyst,which facilitates the charge separation at the interface and improves its photocatalytic activity and stability. | Zhiwei Zhao Xiaofeng Li Kai Dai Jinfeng Zhang Graham Dawson | 2022 | Journal of Materials Science & Technology2022，，22： | 1 |

| 19 | 无机-有机杂化光催化剂:合成、机理及应用显示文摘由无机与有机组分组成的无机-有机杂化材料因其优异的性能及良好的物理化学性质在光催化领域得到了广泛的关注.目前,已经开发的单相光催化剂有很多种,但其很难同时满足宽的光激发范围以及高的光吸收能力和强的氧化还原能力等需求,因此,科研人员开发了很多方法去解决上述问题,主要包括以下两大类.第一类,修饰光催化剂扩大光激发范围以及增强可见光吸收.例如构建固溶体、引入表面缺陷、杂质掺杂、染料敏化和表面等离子体共振等策略.第二类,构建半导体异质结,通过界面处的协同作用有效促进光生电子空穴对的转移与分离.例如type Ⅱ型、直接Z型以及S型异质结等.有机成分与无机成分的杂化是有效解决上述问题的方法之一.大部分有机材料具有成本低、吸光系数高以及比表面积大等优点;但低的强度以及宽的带隙限制了有机材料在光催化上的应用.而大部分无机材料具有高强度、窄带隙以及良好的光学性能.但低韧性和较差的分散性限制了无机材料在光催化上的应用.无机-有机杂化材料不仅保留了无机与有机组分的原有性质,而且界面处组分之间的协同作用会产生新的性质,如高的载流子传输能力和高的光吸收能力等.无机-有机杂化材料是多相材料,其中的一相是纳米材料,从而保留了纳米材料的量子尺寸效应、小尺寸效应、表面效应和宏观量子隧道效应;并且纳米结构的光催化剂相对于体相材料而言,具有比表面积高、载流子输运距离短和电子结构可调等优势.无机-有机杂化光催化材料既保留了高的光吸收能力,又保留了高氧化性的空穴与高还原性的电子,因而在光催化领域的应用越来越广泛.本文综述了无机-有机杂化材料的合成、机理以及在光催化领域的应用.首先,介绍了无机-有机光催化剂的作用、优缺点以及设计原则,讨论了自上而下和自下而上制备无机-有机杂化材料的方法,为设计杂化材料提供思路.其次,对有机组分与无机组分的相互作用力进行分类讨论.再次,阐述了无机-有机杂化材料的优势,讨论了进一步改进无机-有机光催化剂的方法.最后,总结了无机-有机杂化材料在光催化领域面临的问题与挑战,并对未来发展进行了展望. | 杨辉 代凯 张金锋 Graham Dawson | 2022 | Chinese Journal of Catalysis2022，43，8： | 1 |
| 20 | In_(2)O_(3)/Bi_(19)Br_(3)S_(27)S型异质结增强光催化CO_(2)还原显示文摘近年来,半导体催化剂因其较强的氧化还原能力和较好的稳定性而受到广泛关注.然而,光生电子和空穴对易复合和低氧化性导致单一半导体催化剂难以实现实际应用.深入研究表明,S型异质结具有独特的电子和空穴分离机理、强大的氧化还原能力和较强的载流子分离驱动力.本研究以在In_(2)O_(3)纳米球上生长的Bi_(19)Br_(3)S_(27)纳米花为原料,采用水热法合成了In_(2)O_(3)/Bi_(19)Br_(3)S_(27)梯形异质结.这种梯形异质结有效地促进了光生电荷载流子的分离和转移.结果表明,In_(2)O_(3)/Bi_(19)Br_(3)S_(27)复合材料对CO_(2)的还原产率高达28.36μmol h^(-1)g^(-1),分别是In_(2)O_(3)和Bi_(19)Br_(3)S_(27)的19和3.5倍.此外,通过原位漫反射红外傅里叶变换光谱对参与光催化反应的中间体进行了研究,揭示了光催化还原CO_(2)的反应过程.本工作为构建S型异质结光催化剂增强CO_(2)催化还原的方法提供了较好的研究思路. | 卞玉琴 何厚伟 Graham Dawson 张金锋 代凯 | 2024 | Science China Materials2024，67，2： | 0 |
