VISIBLE LIGHT RESPONDING PHOTOCATALYST COMPRISING RARE- EARTH ELEMENT, HYDROGEN MANUFACTURING METHOD USING THE SAME AND DECOMPOSITION METHOD FOR HARMFUL CHEMICAL SUBSTANCE

摘要

PPROBLEM TO BE SOLVED: To obtain a photocatalyst capable of utilizing not only an ultraviolet region but also a visible light region, a means for forming and manufacturing hydrogen by using this photocatalyst in the decomposition of water, or the like, and a harmful substance detoxifying treatment means using the photocatalyst in the decomposition treatment of a harmful substance. PSOLUTION: As a photocatalytic component, a vanadium (V)-containing composite oxide semiconductor represented by the formula: RVOSB4/SB(wherein, R is a Y element or a lanthanide element) is used.
