The CO2 photoreduction process is becoming a promising strategy to solve the energy shortage problem and global warming in recent years. How to promote the separation of photoinduced carriers has attracted attention for the improvement of photocatalytic CO2 reduction. In the present work, an S-scheme heterojunction of Bismuthene/CsPbBr3 quantum dots (Bismuthene/CsPbBr3 QDs) is constructed as the photocatalyst for CO2 conversion. As a result, Bismuthene/CsPbBr3 QDs exhibit an optimal CH4 evolution rate of 43.1 μmol h–1 g–1 with 84.53% selectivity over CH4 under ultraviolet–vis light (UV–vis) irradiation. Construction of the S-scheme heterojunction with a narrow band gap semiconductor is the main factor for improving the photocatalytic performance, as the S-scheme heterojunction can suppress the recombination of photoinduced carriers and retain redox ability. The narrow band gap semiconductor Bismuthene can enhance light absorption abilities. This work probably provides some insights for the designing of heterojunction photocatalysts and the improvement of photocatalytic performance.

“…Bismuthene shows a much higher XRD diffraction peak intensity than CsPbBr 3 QDs, which may cover the diffraction peaks of CsPbBr 3 QDs in Bismuthene/ CsPbBr 3 QDs. 32 The preparation process of Bismuthene/CsPbBr 3 QDs is illustrated in Scheme 1. Initially, the as-prepared Bismuthene is dissolved in ODE to form a uniform solution.…”

“…[270,272] Based on these outstanding properties and enhanced long-term stability, bismuthene has been applied in various optical and photoelectronic devices such as ultrafast pulse generators, all-optical switchers, AOMs, highperformance photodetectors, and optical limiters. [266][267][268][269]273,274] It has been theoretically predicted and experimentally verified that bismuthene can host a 2D TI state. [275][276][277][278][279] The topological properties of bismuthene are stable at room temperature and independent of the number of layers, leading to its application in energy sciences.…”

In recent years, tremendous attention has been paid to the investigation of single-element 2D materials. These 2D materials mainly consist of elements from group IV and group V such as silicene, phosphorene, and antimonene. Together with other four elements from groups III and VI, they are classified as 2D Xenes and exhibit rich optical and optoelectronic properties such as broadband optical response, strong nonlinearity, ultrafast recovery time, and layer-dependent bandgap. 2D Xenes can be easily integrated with microfibers and other optical platforms. On the basis of their attracting characteristics, 2D Xenes have been utilized in various functional devices. In this review, the optical and optoelectronic properties of the most intensively studied 2D Xenes are introduced. Their applications in photonic devices including all-optical modulators, wavelength converters, ultrafast lasers, and photodetectors are explicitly explored. Finally, the challenges and future perspectives of photonic devices based on 2D Xenes are discussed.
