“…As can be seen in the gure, the XRD peak position of the fabricated nanosheets is identical to that of the bulk BP crystal, but the peak intensity differs considerably from that of bulk BP. 38,39 Therefore, the decrease in the XRD peaks of BP nanosheets approves the successful exfoliation of BP through the LPE method.…”

“…Stepwise (S-scheme) heterojunctions have been popular in recent studies for constructing heterojunction systems for photocatalysts. − The S-scheme heterojunction can be visualized macroscopically as a transfer route of e – from lower to higher positions, and it is similar to a Z-scheme heterojunction but retains a stronger redox potential. In general, S-scheme heterojunctions consist of two types of semiconductors: reduced semiconductors (A) and oxidized semiconductors (B).…”

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.

“…To improve the oxidation ability and charge separation, numerous research works construct BP-based S-scheme heterojunctions by hybridizing BP with oxidation photocatalysts such as WO 3 and BiOX. [154][155][156][157] BP-based S-scheme photocatalysts are widely applied to CO 2 reduction because of the high CB position and strong CO 2 adsorption capacity of BP. [158,159] Recently, a 2D/2D BP/Bi 2 WO 6 S-scheme photocatalyst was fabricated to realize synchronous CO 2 conversion and benzylamine (BA) oxidation.…”

Semiconductor photocatalytic technology holds immense promise for converting sustainable solar energy into chemically storable energy, with significant applications in the realms of energy and the environment. However, the inherent issue of rapid recombination of photogenerated electrons and holes hinders the performance of single photocatalysts. To overcome this challenge, the construction of 2D S‐scheme heterojunction photocatalysts emerges as an effective strategy. The deliberate design of dimensionality ensures a substantial interfacial area; while, the S‐scheme charge transfer mechanism facilitates efficient charge separation and maximizes redox capabilities. This review commences with a fresh perspective on the charge transfer mechanism in S‐scheme heterojunctions, followed by a comprehensive exploration of preparation methods and characterization techniques. Subsequently, the recent advancements in 2D S‐scheme heterojunction photocatalysts are summarized. Notably, the mechanism behind activity enhancement is elucidated. Finally, the prospects for the development of 2D S‐scheme photocatalysts are presented.
