Silver bismuthate (AgBiO₃), a potential n-type bismuth-based photocatalyst with ilmenite (perovskite structure) offers remarkable ability for sustainable application. Owing to non-toxic and earth-abundant elements (Ag, Bi, O), the AgBiO₃ photocatalyst is considered to be an eco-friendly alternative to traditional photocatalysts. The presence of mixed valence states Bi³⁺ with a filled 6 s orbital and Bi⁵⁺ with an empty 6 s orbital in AgBiO₃ photocatalyst narrows the band gap and facilitates a broader light absorption range. However, bare AgBiO₃ exhibits some disadvantages like fast e^–/h⁺ pair recombination and is prone to photo-corrosion, which limits its photocatalytic performance and restricts its practical utility. To overcome these limitations, heterojunction formation (Type-II, Z-scheme, and S-scheme) and defect generation play an indispensable role in boosting the photo-efficiency of the bare AgBiO₃ via enhanced light absorption, higher quantum efficiency, improved charge transference, and reduced charge recombination as validated by EIS and PL spectroscopy.
