In latest events, water pollution has posed an immense threat, and its sustainable treatment is a topic of concern. Among myriad of water treatment, research community has lensed towards sustainable heterogeneous photocatalysis especially, inorganic semiconductors. Bismuth tungstate a pristine Aurivillius compound with unique crystal structure, exceptional photochemical stability, and strong redox abilities but minimum visible light absorption and quick carrier recombination are its caveats, these caveats are circumvented by synthesizing BiOX (X=F, Cl, Br and I) composites with surface modifiers, doping with hetero atoms (metals and non‐metals), construction of the heterojunction and amalgamation of carbon materials. The heart of this review is strategic engineering of flower‐like morphology photocatalyst synthesis and optical properties, it also discusses the charge transfer kinetics, photocatalytic performance, and durability. The flower‐like morphology highlighted in this review is due to its ability to harvest light, providing larger specific surface area which introduces more active sites and efficient excitons generation. The comprehensive tabulated data in this review will help the actively engaged research community in Bismuth heterogenous photocatalysis. It also sheds light on the future view of environmental remediation via photocatalytic developments.

Given the environmental hazards posed by low-concentration NOx emissions, visible-light-driven photocatalytic technologies have been widely studied for the removal of NOx. Constrained by the insufficient light absorption range and rapid recombination of carriers of an individual photocatalyst, the construction of heterojunctions has emerged as a promising strategy to bolster photocatalytic reaction kinetics. However, traditional approaches for fabricating heterojunctions frequently result in interfaces that are loosely connected and poorly contacted, greatly limiting the photocatalytic performance of the heterojunctions. Therefore, in this research, a BiOI/Bi 5 O 7 I p-n heterojunction was successfully constructed through an in situ phase transformation approach, demonstrating exceptional photocatalytic performance in the purification of NO under visible light irradiation. Benefiting from the interfacial electric field formed at the tightly formed heterojunction interface, significant suppression of carrier recombination and improved separation efficiency were achieved, as evidenced by both in situ DRIFTS and theoretical calculations. This strategy can also inspire the utilization of in situ heterojunction construction to modulate the electronic structure of conventional bismuth-based semiconductors, enhance charge transfer at the interface, and improve the photocatalytic activity.
