Artificial photosynthetic solar-to-chemical cycles enable an entire environment to operate in a more complex, yet effective, way perform natural photosynthesis. However, such artificial systems suffer from lack of well-established photocatalysts with the ability harvest solar spectrum and rich catalytic active-site density. Benefiting extensive experimental theoretical investigations, this bottleneck may be overcome by devising photocatalytic platform based on metal sulfides predominant electronic, physical, chemical properties. These tunable properties can endow them abundant active sites, favorable light utilization, expedited charge transportation for conversion. Here, it is described how some vital lessons extracted previous investigations are employed promote further development photosynthesis, including water splitting, CO2 reduction, N2 pollutant removal. Their functions, properties, synthetic strategies, emerging issues, design principles, intrinsic functional mechanisms redox reactions discussed detail. Finally, associated challenges prospects utilization highlighted future trends photocatalysis envisioned.

Abstract Sluggish charge kinetics in photocatalysts and slow hole transfer oxidation half‐reaction severely limit the photocatalytic activity of hydrogen evolution. ZnIn 2 S 4 with an asymmetrical layered structure [S–In]–[S–In–S]–[Zn–S] unit cell is a promising material offering crystal polarization to overcome limitation; however, polarization‐induced internal electric field by this remains largely unexplored. Herein, engineering polarity intensity microscopic units demonstrated for first time. Specifically, ultrathin nanosheets are employed establish Ni 12 P 5 /ZnIn ‐O (NP/ZIS‐O) system powerful bulk interface cascade oxygen doping ohmic junction. Enabled such design, photogenerated electrons can rapidly migrate NP active sites, suppressing electron‐hole pair recombination on ZIS‐O. To further inefficient half‐reaction, preferential dehydrogenation α‐CH bond benzyl alcohol utilized as vehicle facilitate transfer. As result, remarkably enhanced H generation 15.79 mmol g –1 h achieved NP/ZIS‐O, which 8.16‐fold higher than that pristine . Meanwhile, value‐added product, benzaldehyde be produced at rate 17.63 This work presents collaborative strategy behavior features, provides insights into materials design toward production organic synthesis from angle kinetics.
