A photocatalyst is a substance that can be substances with light to remove harmful substances such as organic compounds and bacteria. Currently, titanium oxide (TiO₂) is mainly used as a photocatalyst. However, TiO₂ has problems such as its weak effect other than ultraviolet rays. In this study, we focused on graphitic carbon nitride (g-C₃N₄) and bismuth vanadium oxide (BiVO₄), which show a catalytic reaction even in visible light, and combined them with g-C₃N₄ / BiVO₄. The powder was prepared by two synthetic methods. Then, we reported on the catalytic reaction under visible light irradiation.and SEM image .
