【摘要】 通过高温煅烧ZnSn（OH）₆前驱体制备了双壳中空立方体结构的ZnSnO₃（ZSO），进而采用水热法将CdIn₂S₄（CIS）纳米晶包裹在ZSO表面，成功制备了CdIn₂S₄/ZnSnO₃（CIS/ZSO）异质催化剂。活性产氢实验结果表明，CIS、ZSO物质的量之比为12%时制备的12%CIS/ZSO具有优异的光催化产氢性能，在3 h内产氢量为1 676.48μmol·g^-1，分别是ZSO和CIS的12倍和8倍。ZSO光催化析氢反应活性的增强归因于CIS/ZSO异质结构的成功构建，异质界面的形成显著提高了光生电子/空穴对的分离效率，降低了其复合率。通过对电荷转移路径的分析，提出了可能的反应机理。更多还原

【Abstract】 The double shell hollow cube structural ZnSnO₃（ZSO） was prepared by high-temperature calcination with ZnSn（OH）₆ as a precursor.Then,the CdIn₂S₄（CIS） nanocrystalline was wrapped on the surface of ZSO by a hydrothermal method.Thus CdIn₂S₄/ZnSnO₃（CIS/ZSO） heterostructures were successfully prepared.The photocatalytic hydrogen evolution reaction（HER） result indicated that the as-prepared 12% CIS/ZSO heterostructure obtained with the molar ratio of CIS to ZSO of 12% exhibited excellent photocatalytic H₂-production activity with the hydrogen yield of 1 676.48 μmol·g^-1 for 3 h,about 12 times and 8 times of original ZSO and CIS,respectively.The enhanced activity of the ZSO photocatalytic HER was attributed to the successful construction of the CIS/ZSO heterostructure.The formation of the CIS/ZSO heterostructural interface significantly improved the separation efficiency of photogenerated electron/hole pairs and reduced their recombination rate.Furthermore,the possible reaction mechanism was proposed by analyzing the charge transfer pathway.更多还原
