Abstract Solar fuel synthesis is intriguing because solar energy abundant and this method compensates for its intermittency. However, most photocatalysts can only absorb UV‐to‐visible light, while near‐infrared (NIR) light remains unexploited. Surprisingly, the charge transfer between ZnO CuInS 2 quantum dots (QDs) transform a NIR‐inactive into NIR‐active composite. This strong response attributed to increased concentration of free carriers in p‐type semiconductor at interface after migration , enhancing localized surface plasmon resonance (LSPR) effect NIR . As paradigm, ZnO/CuInS heterojunction used H O production coupled with glycerin oxidation demonstrates supreme performance, corroborating importance efficient transfer. Mechanistic studies through contact potential difference (CPD), Hall test, finite element (FEM) calculation allow direct correlation approach bypasses general issues, thereby stepping forward ambitious goal harnessing entire spectrum.

Abstract Near‐infrared (NIR) light‐driven photocatalysis provides a promising solution to the inherent limitations of conventional ultraviolet (UV) and visible‐light photocatalysis, such as shallow penetration, photodamage from high‐energy irradiation, limited selectivity. However, effective strategies for achieving NIR remain scarce. Here, novel strategy that achieves with significantly enhanced selectivity is reported through lanthanide nanocrystal‐mediated photosensitization. A composite nanocatalyst, comprising NaNdF 4 nanocrystals Zn(II) phthalocyanine organic photosensitizers designed, where absorb 808 nm light transfer energy directly via lanthanide‐mediated triplet sensitization. This approach enables selective functionalization substrates increased yields reduced side‐product formation compared UV/visible excitation. The arises controlled generation superoxide anions (O 2 − ) reactive oxygen species (ROS) minimized substrate photoactivation. targeted dehydrogenation C─N coupling reactions diverse N‐heterocyclic substrates, including halogen‐substituted compounds are typically prone undesired side reactions. findings establish versatile improving in photocatalytic transformations, opening new opportunities light‐sensitive synthesis sustainable catalysis.
