Advancements and Prospects of Near-infrared-light Driven Co2 Reduction Reaction

Jiaqi Xu

In the realm of photoconversion of CO2 into high-value chemicals, the importance of near-infrared (NIR) light is gradually gaining recognition. Relative to ultraviolet (UV) and visible light, NIR light (700-2500 nm), accounting for ca. 50% of solar energy, ...
