Abstract: The production of hydrogen by direct water splitting using a catalyst and sunlight is an ideal future energy source, independent of fossil reserves. During the past 40 years, various inorganic semiconductors and molecular assemblies have been developed as catalysts for hydrogen production from water under visible light illumination. However, for an economical utilization of water and solar energy, catalysts that are sufficiently efficient, stable, cheap, and capable of harvesting the abundant visible light are required. We have found that an abundant material, polymeric carbon nitride, can activate hydrogen production from water under visible light irradiation. The facile synthesis of the melon-based polymeric carbon nitride from simple liquid precursors and monomers allows easy engineering of carbon nitride materials to achieve better photocatalytic performance via several processing routes and methods, like doping, templated synthesis, copolymerization, hot-fluid annealing, and heterojunction design.1,2 The results represent an important step in photosynthesis of solar hydrogen fuels and chemicals where conjugated polymer semiconductors could be used as photocatalysts.
