摘要

通过对含有导电碳纳米管的悬浊液进行过滤，观察到由窄带隙SrTaO2N （2.1 eV）和La5Ti2Cu0.9Ag0.1O7S5 （1.8 eV）组成的光催化剂片材的Z-scheme水分裂现象。在SrTaO2N上预负载碳纳米管，并对负载的助催化剂进行细化，使得光催化剂片在430 nm处的表观量子产率为0.13%，优于以Au为导电材料的粒子转移法制备的光催化剂片。该方法提供了一种简单、低成本的方法，用于制造基于长波可见光响应非氧化物的光催化剂片，用于Z-scheme水分解。

Enhancement of Z-Scheme Water Splitting Using Photocatalyst Sheets Fabricated by Simple Filtration of Long-Wavelength Visible-Light-Responsive Nonoxides and Carbon Nanotubes

Z-scheme water splitting was observed for photocatalyst sheets consisting of narrow-band-gap SrTaO₂N (2.1 eV) and La₅Ti₂Cu_0.9Ag_0.1O₇S₅ (1.8 eV) immobilized by filtration of their suspension containing conductive carbon nanotubes. Preloading of carbon nanotubes on SrTaO₂N and refinement of cocatalyst loading allowed the photocatalyst sheet to split water with an apparent quantum yield of 0.13% at 430 nm, which was superior to that reported for the photocatalyst sheet prepared by the particle transfer method using Au as the conductive material. The proposed method offers a facile, low-cost approach for the fabrication of photocatalyst sheets based on long-wavelength visible-light-responsive nonoxides for Z-scheme water splitting.
