通过油胺（OA）辅助溶剂热法成功合成了具有 3D 分层柿子形状的六方 ZnIn2S4 光催化剂。析氢实验表明，所获得的分级ZnIn2S4具有良好的光催化活性，例如当Pt负载量为3%时,产氢率达到220.45 μmol h(-1),量子产率达到13.16%。进一步精细调整所得ZnIn2S4晶体的暴露面百分比，发现金属离子封端的{006}面的增加会提高其光催化活性，并研究了晶体结构与光催化性能之间的关系。版权所有 (C) 2012，Hydrogen Energy Publications, LLC。由爱思唯尔有限公司出版。保留所有权利。
Hexagonal ZnIn2S4 photocatalysts with 3D-hierarchical persimmon-like shape have been successfully synthesized via an oleylamine (OA)-assisted solvothermal method. Hydrogen evolution experiments revealed that the obtained hierarchical ZnIn2S4 possessed good photocatalytic activity, e.g. hydrogen production rate reached to 220.45 mu mol h(-1) and the quantum yield was up to 13.16% when 3% Pt was loaded. Further delicate tuning the percentage of exposed facet of the obtained ZnIn2S4 crystals, it was found that the increase of {006} facets, terminated by metal ions, would improve their photocatalytic activity, and the relationship between the crystal structure and photocatalytic properties had been studied.
