Tunable Band Engineering Management on Perovskite MAPbBr3/COFs Nano‐Heterostructures for Efficient S–S Coupling Reactions

Qianying Lin,

et al.

Abstract: Efficient artificial photosynthesis of disulfide bonds holds promises to facilitate reverse decoding of genetic codes and deciphering the secrets of protein multilevel folding, as well as the development of life science and advanced functional materials. However, the incumbent synthesis strategies encounter separation challenges arising from leaving groups in the ─S─S─ coupling reaction. In this study, according to the reaction mechanism of free‐radical‐triggered ─S─S─ coupling, light‐driven heterojunction fun… Show more

“…The heterojunction structure can not only inhibit the recombination of photogenerated carriers, but also stabilize the material. 12,13 In a traditional type II heterojunction, while the efficient separation of photogenerated electrons and holes is achieved, the redox ability of the semiconductor is inevitably weakened. 14,15 In recent years, Z-scheme heterojunctions have attracted extensive attention due to their ability to enhance the separation efficiency of photogenerated carriers, while also retaining the strong redox capability of semiconductors.…”

“…4,11,12 Organic-inorganic hybrid perovskites, such as MAPbBr 3 , have been regarded as an ideal candidate for photocatalytic energy conversion reactions due to their long diffusion length, tunable band structure, and large light absorption coefficient. 2,3,[13][14][15][16][17] Unfortunately, the poor separation efficiency and serious recombination of the photo-excited charge carriers in MAPbBr 3 greatly limited their applications, which could be overcome by the construction of a heterostructure with two or more semiconductors with different band structures and lattice constants. 13,15 Consequently, a series of MAPbBr 3 -based heterostructures, such as MAPbBr 3 -g-C 3 N 4 , MAPbBr 3 -MXene, and MAPbBr 3 -COFs, for photocatalytic degradation and water splitting were proposed.…”
