Photocatalysis is a process of accelerating a chemical reaction using light energy, which has the potential to provide sustainable and green technologies for a wide range of applications. Metal oxides, such as CeO2, ZnO, and Bi2O3, are important photocatalysts due to their excellent catalytic properties and ease of synthesis. However, these metal oxides have some limitations, such as low photocatalytic efficiency, rapid recombination of photo-induced...
