“…To date, diverse light-absorbing photocatalysts known for their favorable photochemical and electrical properties have been widely developed as valuable materials to reduce CO2 to CO or hydrocarbons [5][6][7]. However, owing to the inert scaling properties of CO2, the reduction is frequently restricted by the strong chemical bonding and inactive carrier excitation, hugely limiting the practical applications of CO2 reduction [8,9]. In addition, photocatalysts are typically restricted by poor CO2 adsorption and visible-light responsiveness because their structural control is challenging, and they have a wide bandgap position [10][11][12][13][14].…”

Solar‐driven conversion of CO2 into high value‐added fuels is expected to be an environmental‐friendly and sustainable approach for relieving the greenhouse gas effect and countering energy crisis. Metal sulfide semiconductors with wide photoresponsive range and favorable band structures are suitable photocatalysts for CO2 photoreduction. This review summarizes the recent progress on metal sulfide semiconductors for photocatalytic CO2 reduction. First, the fundamentals, mechanisms and some principles, like product selectivity, of photocatalytic CO2 reduction are introduced. Then, according to the elemental composition, the metal sulfide photocatalysts applied for CO2 reduction are classified into binary (CdS, ZnS, MoS2, SnS2, Bi2S3, In2S3,Cu2S, NiS/NiS2, and CoS2), ternary (ZnIn2S4, CdIn2S4, CuInS2, Cu3SnS4, and CuGaS2), and quaternary (Cu2ZnSnS4) systems, in which their crystal structures, photochemical characteristics, and photocatalytic CO2 reduction applications are systematically demonstrated. Especially, the diverse modification strategies for improving the activity and product selectivity of photocatalytic CO2 reduction on these metal sulfides are summarized. Finally, the current challenges and future directions for the development of metal sulfide photocatalysts for CO2 reduction are proposed. This review is expected to serve as a powerful reference for exploiting high‐efficiency metal sulfide photocatalysts for CO2 conversion and furthering related mechanism understanding.

Broadening the absorption of light to the near‐infrared (NIR) region is important in photocatalysis to achieve efficient solar‐to‐fuel conversion. NIR‐responsive photocatalysts that can utilize diffusive solar energy are attractive for alleviating the energy crisis and environmental pollution. Over the past few years, considerable progress on the component and structural design of NIR‐responsive photocatalysts have been reported. This study aims to systematically summarize recent progress toward the material design and mechanism optimization of NIR‐responsive photocatalysts in this area. Depending on the main strategies for harvesting NIR photons, NIR‐responsive photocatalysts can be categorized as direct NIR‐light photocatalysts, indirect NIR‐light photocatalysts, and photothermal photocatalysts. Furthermore, the construction and application of different NIR‐responsive photocatalytic systems are summarized. Conclusions and perspectives are presented to further explore the potential of NIR‐responsive photocatalysts in this field.
