Abstract

Development of a near-infrared (NIR) light-induced hydrogen (H2) evolution system is indispensable for constructing a sustainable society wherein the utilization of solar energy is maximized. Here, we report NIR light-driven H2 evolution catalyzed by a combination of a diprotonated saddle-distorted porphyrin as a photosensitizer and platinum nanoparticles as a H2-evolving catalyst. The quantum yield at 710 nm was determined to be 17%, which is the highest value among photocatalytic H2-evolution systems ever reported.
