Towards Full‐spectrum Photocatalysis: Extending to the Near‐infrared Region

Abstract The ability to use the full solar spectrum energy in photocatalytic processes for environmental remediation and energy production has attracted worldwide attention. Efficient harvesting of near‐infrared (NIR) photons, especially in the wavelength range beyond 800 nm, is one of the main driving forces in photocatalytic research. The design of appropriate photocatalytic systems for wide‐range light‐harvesting from the UV to NIR regions is a promising method of maximizing the efficiency of solar energy utilization. This review comprehensively summarizes the recent progress in full‐solar‐light‐driven photocatalytic systems, including several strategies to harness NIR light and thermal energy. The corresponding photocatalytic mechanisms and design of binary or ternary heterogeneous systems are discussed in detail. Moreover, future perspectives and challenges are presented to inspire the development of further innovations in full‐solar‐light‐driven photocatalysis.
