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.
