Abstract Novel and efficient copper-implanted ZnO nanorod/5,10,15,20-tetrakis(4-sulfophenyl)porphyrin composite photocatalysts (ZnO NR-Cu-TSPP) were facilely fabricated. The assembly mechanism was investigated and showed that the TSPP was anchored onto the ZnO NR-Cu through dual interaction, hydrogen bond and coordination interaction. Importantly, the ZnO NR-Cu-TSPP nanocomposite exhibited high photocatalytic activity on account of extended light absorption and greatly enhanced charge separation at the heterointerface. The photocatalytic mechanism revealed that, with the small sized Cu as interfacial linker, not only the interaction between ZnO NR and TSPP was strengthened, but also more active sites for photocatalytic H2 evolution were produced. Furthermore, by the introduction of a certain amount of TSPP, the photocatalytic activity of the nanocomposite can be significantly enhanced, which is higher than those controlled porphyrins with other substituents. Moreover, the composite showed a superior stability according to the cycling tests. This work provides a new idea for fabricating high efficient nano photocatalysts for hydrogen production.

ZnO纳米棒/磺基苯基卟啉纳米复合材料容易嵌入特殊铜以改善光催化析氢

摘要 制备了新型高效的铜植入ZnO纳米棒/5,10,15,20-四(4-磺苯基)卟啉复合光催化剂(ZnO NR-Cu-TSPP)。研究了组装机制，结果表明 TSPP 通过双相互作用、氢键和配位相互作用锚定在 ZnO NR-Cu 上。重要的是，ZnO NR-Cu-TSPP 纳米复合材料由于延长的光吸收和大大增强异质界面的电荷分离而表现出高光催化活性。光催化机理表明，以小尺寸的 Cu 作为界面连接剂，不仅增强了 ZnO NR 与 TSPP 之间的相互作用，而且产生了更多的光催化析氢活性位点。此外，通过引入一定量的 TSPP，纳米复合材料的光催化活性可以显着提高，高于那些具有其他取代基的受控卟啉。此外，根据循环测试，该复合材料显示出优异的稳定性。该工作为制备高效的制氢纳米光催化剂提供了新思路。
