“…To enhance the photocatalytic NO removal performances of Bi-based photocatalysts, many heterojunctions, e.g., Bi 2 O 2 CO 3 /ZnFe 2 O 4 , Bi 2 O 3 /g-C 3 N 4 , SrTiO 3 /BiOI, and TiO 2 /BiOCl, have been constructed. The photocatalytic mechanism and detailed types of heterojunctions are elucidated/summarized as Z-scheme heterojunctions, S-scheme heterojunctions, and p–n heterojunctions based on the performance and charge-transfer mechanisms of the involved photocatalysts. − …”

Nitrogen oxides (NO x , ∼95% NO) are significant atmospheric pollutants that contribute to environmental issues like acid rain and ozone layer depletion. The traditional remediation methods of physical/chemical adsorption and postcombustion reduction techniques fall short in effectively removing gaseous NO at parts per billion (ppb) levels. Consequently, photocatalysis for NO elimination has garnered intensive attention for its cost-effectiveness, efficiency, and ecofriendly attributes. Within the emerging nanomaterials for photocatalytic NO removal, 2D bismuth-based (Bi-based) photocatalysts are pivotal due to their distinctive electronic and structural characteristics. Nonetheless, a comprehensive review of the mechanisms and efficacy of NO removal via 2D Bi-based photocatalysts is still lacking. This review endeavors to fill that gap, elucidating the possible reaction pathways employed by 2D Bi-based nanomaterials for photocatalytic NO oxidation or reduction. Furthermore, it extends to highlight the main factors influencing their photocatalytic efficiencies and summarize three primary modification strategies for enhancement of the photocatalytic activities of 2D Bi-based nanomaterials, encompassing defect engineering, elemental doping, and the construction of heterojunctions. Finally, this review culminates with a forward-looking perspective in developing high-performance 2D Bi-based photocatalysts for NO removal, which underscores existing challenges and sparks new ideas for future work.

“…[67] By using KBiO 3 as precursor, rodlike Bi 4 O 7 could be prepared through hydrothermal route at 140 °C, and further, Bi 4 O 7 /BiOCl composites were obtained by in situ etching using diluted HCl solution. [68] By in situ sulfidation of Bi 4 O 7 , amorphous/ crystalline contact Bi 2 S 3 /Bi 4 O 7 heterostructure was successfully synthesized, which exhibited higher Cr(VI) reduction and RhB oxidation activity than pure Bi 4 O 7 , owing to improved visiblelight response and photogenerated carriers transport. [69] The other reported composites like Bi 4 O 7 /Bi 2 O 2 CO 3 synthesized by hydrothermal-calcining method [70] and δ-Bi 2 O 3 /Bi 4 O 7 obtained through hydrothermal-precipitation route [71] also presented enhanced photocatalytic activity as compared to their single components.…”

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.
