摘要：TiO_(2)is a promising photocatalyst with limited use in practical applications owing to its wide bandgap,narrow light response range,and rapid recombination of photoexcited *** address these limitations,a novel 1D/2D TiO_(2)/ZnIn_(2)S_(4)heterostructure was designed according to the principles of the S-scheme *** TiO_(2)/ZnIn_(2)S_(4)(TZISx)hybrids prepared via a hydrothermal method afforded significant improvement in photocatalytic hydrogen evolution(PHE)in comparison to pristine TiO_(2)and ZnIn_(2)S_(4).In particular,the optimal TZIS2 sample(mass ratio of ZnIn_(2)S_(4)to TiO_(2)was 0.4)exhibited the highest PHE activity(6.03 mmol/h/g),which was approximately 3.7 and 2.0 times higher than those of pristine TiO_(2)and ZnIn_(2)S_(4),*** improvement in the PHE of the TZIS2 sample could be attributed to the formation of an intimate heterojunction interface,high-efficiency separation of charge carriers,abundant reactive sites,and enhanced light absorption ***,theoretical and experimental results demonstrated that the S-scheme mechanism of interfacial electron transfer in the TZISx composites facilitated the transfer and separation of photoexcited charge carriers,resulting in more isolated photoexcited electrons for the PHE reaction.

摘要：富勒烯及其衍生物因具有多维电荷传输特性和与给体材料形成独特的相分离结构等特点,在有机光伏领域占据主导地位。然而,富勒烯类受体材料本身也有一些难以克服的缺点,如可见光范围内吸收能力弱、修饰困难、成本高等,进而限制了器件性能的提高和规模化使用。非富勒烯类小分子受体材料的研究引起越来越多的重视。研究者可借助丰富的化学手段,设计合成出具有特定聚集态形貌和优异性能的有机小分子及其寡聚物。本文总结了近几年关于苝四甲酰二亚胺类、吡咯并吡咯二酮类、苯并噻二唑类等几类性能相对优异的非富勒烯类有机小分子受体材料的最新研究进展,从分子结构上对其性能进行了剖析,对高性能受体材料的设计合成具有一定的指导意义。最后,讨论了提高非富勒烯类有机小分子受体材料器件性能的主要因素及其研究前景。
