单晶WO3/红磷S型异质结的构建及光催化活性研究
Construction and Photocatalytic Activity of Monoclinic Tungsten Oxide/Red Phosphorus Step-scheme Heterojunction
摘要
Abstract
S-scheme heterojunction has been extensively investigated for hydrogen evolution and environmental pollution issues.In this study,a monoclinic WO3/hydrothermally treated red phosphorus(HRP)S-scheme composite was prepared by hydrothermal method.XPS and EPR characterization confirmed that the monoclinic WO3/HRP composite formed S-scheme heterojunction.5%WO3/HRP composite displayed the optimal photocatalytic activity under visible light irradiation,and its degradation rate of Rhodamine B(RhB)reached 97.6%after 4 min of visible light irradiation,while its hydrogen evolution rate reached 870.69 μmol·h-1·g-1 which was 3.62 times of that of pure HRP.This could be ascribed to the tight interfacial bonding between WO3 and HRP,and the formation of S-scheme heterostructure,enabling rapid separation of photogenerated carriers and therefore improving the strong redox capacity.This study provided a promising RP-based photocatalyst to meet the demand for clean energy and drinking water.关键词
