A bismuth-based material serves as an interesting and innovative class of visible-light-driven photocatalysts that have paid a lot of attraction towards exceptional photo-oxidation capacity. The great progress for the decomposition of water oxidation and organic contaminants have been documented with the aid of photocatalytic strategies. At present, the classification of Bi-based photocatalysts can be given as bismuth metal, binary sulfides, multicomponent oxides, bismuth oxyhalides, binary oxides, and so forth. Although Bi provides advanced outcomes for photocatalysts towards energy development and environmental remediation, their productivity still is not at supreme level. Prompting recombination of e--h+ pairs (photogenerated) along with characteristic structural instability has restricted its applied usage. To resolve these issues, some strategies have been tendency to bismuth-rich strategy, elemental doping …
