“…The photocatalytic activity of KBiO3 showed 100% discoloration of MB within 120 min KBiO3 obtained by the sonochemical method and 67% degradation of CPFX was obtained by KBiO3 synthesized by hydrothermal method [145]. The influence of the enhanced charge separation was displaced in the photocatalytic reaction.…”

The development of new generation photocatalytic materials used for the betterment of human as well as environment. Perovskites and perovskites related nano-hetero-junction shows great interest for photocatalytic organic and inorganic pollutant removal. This chapter discusses its crystalline structures varying from cubic (high symmetry) to triclinic (very low symmetry). Various methods have been utilized for synthesis of perovskites such as sol-gel, hydrothermal, vapor deposition methods, solid-state reaction routs from oxide and high pressure technique. The first technique is used for the synthesis of perovskite is ceramic route in which the mixture of oxide was treated at high temperature and processed later by ceramic powder method. Various photocatalyst such as nitrides, sulphides, phosphides, oxide and mixed oxide are employed for photocatalytic water splitting or hydrogen generation. Future perspectives of perovskite-related photocatalyst are included in this chapter.

Bi‐based semiconducting materials have received tremendous attention due to their availability, non/low toxicity, ecological friendship, rich chemical forms, and good visible‐light‐driven photocatalytic performance. As compared to the commonly investigated trivalent bismuth (Bi(III))‐based photocatalysts, non‐trivalent bismuth‐based materials (NTBBMs), such as BiO2−x, Bi2O4−x, Bi4O7, NaBiO3, and so on, exhibit excellent visible‐light‐ and even full‐spectrum‐driven photocatalytic activity as they hold narrow bandgap, suitable positions of conduction band and valence band, and relatively redox‐sensitive structures. In this review, it is attempted to summarize the recent progress in the preparation, microstructures, and modification strategies of various NTBBMs‐based photocatalysts. At the end, the advantages and disadvantages of NTBBMs‐based photocatalysts and future perspectives are presented.
