“…Photocatalysis is regarded as a potentially "green" chemistry technique that can exploit inexhaustible solar energy to decompose toxic pollutants and generate hydrogen from water [1,2]. In this regard, numerous researchers are drawn to this technology [3][4][5][6][7]. Admittedly, the core of this technology is semiconductor photocatalysis, where solar energy is used to induce the generation of electron-hole pairs in semiconductors, which then participate in redox reactions [8][9][10].…”

“…The above DFT calculations suggest that the BP QDs are able to improve the CRR performance of BP/ZIS composite through optimizing the adsorption energies of *H, *COOH and *HCOO intermediates on the surface of photocatalyst. For the syngas production in alkaline or neutral solution, the hydrophobic surface of BP, [49] as well as the unique E CB of BP that is closer to the redox potential of CO 2 ‐to‐CO reduction than that of H 2 evolution, [18a, 50] may further contribute to the promoted kinetics of CO production.…”

Solar-driven syngas production by CO 2 reduction provides as ustainable strategy to produce renewable feedstocks. However,t his promising reaction often suffers from tough CO 2 activation, sluggish oxidative half-reaction kinetics and undesired by-products.H erein, we report af unctionoriented strategy of deliberately constructing black phosphorus quantum dots-ZnIn 2 S 4 (BP/ZIS) heterostructures for solardriven CO 2 reduction to syngas,p aired with selectively oxidative CÀNb ond formation, in one redox cycle.T he optimal BP/ZIS heterostructure features the enhanced chargecarrier separation and enriched active sites for cooperatively photocatalytic syngas production with at unable ratio of CO/ H 2 and efficient oxidation of amines to imines with high conversion and selectivity.T his prominent catalytic performance arises from the efficient electronic coupling between black phosphorus quantum dots and ZnIn 2 S 4 ,a sw ell as the optimizeda dsorption strength for key reaction intermediates, as supported by both experimental and theoretical investigations.Wealso demonstrate asynergistic interplaybetween CO 2 reduction and amine dehydrogenation oxidation,r ather than simply collecting these two single half-reactions in this dualfunctional photoredoxs ystem.

Photocatalytic carbon dioxide (CO2) reduction is a sustainable and green strategy for the conversion of CO2 into hydrocarbon solar fuels, whereas its large‐scale application is severely restricted by lack of highly effective photocatalysts. Ultrathin 2D materials with tunable electronic structure display great potential towards photocatalytic CO2 reduction. However, the photocatalytic performance still remains unsatisfied due to high activation energy of CO2 molecules on catalytic sites. To this end, surface vacancy engineering can endow coordinately unsaturated sites as actively catalytic sites for CO2 molecules chemisorption and activation. In this review, we focus on vacancy‐engineered ultrathin materials for CO2 photoreduction. Different vacancies with classified anion vacancies, cation vacancies, vacancy pairs, voids, and their corresponding role in CO2 photoreduction are proposed. The different strategies based on vacancy engineering, including direct modulation of vacancy concentrations, refining vacancy states by heteroatom, and vacancy‐engineered heterostructure, are presented. Finally, the future developments and their associated challenges concerning defective ultrathin 2D materials are discussed.
