摘要：Rational design and construction of step-scheme(S-scheme)photocatalyst has received much attention in the field of CO_(2) reduction because of its great potential to solve the current energy and environmental crises.In this study,a series of plate-like WO_(3)/CuBi_(2)O_(4)(WO/CBO)photocatalysts were synthesized.The CO and CH4 yields over optimal composite reached 1,115.8 and 67.2μmol/m2 after 9 h visible light illumination(λ>400 nm),which was higher than those of two pure catalysts in CO_(2) photoreduction.The product yields slightly decreased in the 7th cycling.Besides,the staggered band structure of heterojunction was characterized by diffuse reflectance spectroscopy(DRS)and valence band-X-ray photoelectron spectroscopy(VB-XPS),and a S-scheme charge transfer mechanism was verified by detecting electron spin resonance(ESR)and XPS result about surface composition of WO/CBO catalyst in dark or light.This work may be useful for rational designing of S-scheme photocatalyst and provides some illuminating insights into the S-scheme transfer mechanism.
