Abstract

Selecting a suitable photocatalyst to establish the Z-scheme heterojunction which is accompanied by effective photogenerated hole and electron separation, is one of the advantageous strategies for efficient photocatalytic solar energy conversion. Therefore, we prepared a ZnInSe nanoparticles photocatalyst to build a double Z-scheme heterojunction with mixed-phase TiO nanofibers, boosting photocatalytic solar fuel preparation. The result of X-ray photoelectron spectroscopy confirmed the existence of interfacial chemical bonds and internal electric fields. The interfacial Ti-Se bond is regarded as a channel and the internal electric field serves as the driving force for electron transfer. And the composite photocatalyst exhibits a great hydrogen evolution rate of 0.11 mmol g h. From a forward-working perspective, this work proposes a ZnInSe nanoparticles photocatalyst for efficient solar fuel conversion, promoting the application of bimetallic selenide photocatalyst in the field of photocatalysis.

摘要

选择合适的光催化剂以建立伴随有效光生空穴和电子分离的Z型异质结，是实现高效光催化太阳能转换的有利策略之一。因此，我们制备了一种ZnInSe纳米颗粒光催化剂，以与混合相TiO纳米纤维构建双Z型异质结，从而促进光催化太阳能燃料的制备。X射线光电子能谱结果证实了界面化学键和内部电场的存在。界面Ti-Se键被视为一个通道，内部电场作为电子转移的驱动力。并且该复合光催化剂表现出0.11 mmol g h的高析氢速率。从正向研究的角度来看，这项工作提出了一种用于高效太阳能燃料转换的ZnInSe纳米颗粒光催化剂，推动了双金属硒化物光催化剂在光催化领域的应用。
