Near‐Infrared‐Responsive Photocatalysts

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. Near‐infrared (NIR)‐driven photocatalysts are extensively explored to promote their solar‐energy utilization and improve their photocatalytic performance. Accordingly, diverse photocatalytic systems have been specifically designed to harvest the long‐wavelength NIR light. These NIR‐responsive photocatalyst systems have potential applications in various fields, including H2 production, CO2 photoreduction, pollutant degradation, and photocatalytic disinfection.
