Carbon-free solar fuel production driven by solar energy has become a holy grail for a future sustainable world. In recent years, much interest has been centered on hydrogen peroxide (H2O2), a carbon-free solar fuel that is superior to hydrogen (H2) in terms of transportation and direct use in membrane-free fuel cells. Thus, H2O2 production using solar energy from pure water over visible-light-active photocatalysts is a more sustainable approach than existing anthraquinone-based processes. Herein, for the first time, a metal-free heptazine-based porous polymeric network (HMP-PPR) featuring heptazine and porphyrin units bridged through –NH– bonds is developed. Under simulated sunlight, HMP-PPR shows nearly 9 times higher H2O2 production than graphitic carbon nitride (g-CN). Further, HMP-PPR stably generates 750 μmol g−1 H2O2 over propan-2-ol in 24 h. Interestingly, under natural sunlight, it produces 151 μmol g−1 H2O2 from pure water in 4 h through both a two-electron oxygen reduction reaction and two-electron water oxidation. Such exciting results are explained based on the unique band positions of the material, oxygraph analysis, and theoretical studies. This study explains the importance of heptazine-based porous polymeric networks in liquid solar fuel production.

Metal-free organic polymer photocatalysts have attracted dramatic attention in the field of visible light-induced hydrogen evolution reaction (HER). Herein, we showed a polymeric O-linked heptazine polymer (OLHP) decorated with S, N co-doped graphene quantum dots (S,N-GQDs) as a photosensitizer to generate hydrogen upon quantum dot sensitization. Both of these heptazine-based systems show effective photosensitization with strong π–π interactions and enhanced photocatalytic H2 generation (24 times) as metal-free systems. Electrochemical impedance and optical measurements show effective charge transfer kinetics with decreased charge recombination, which is responsible for the enhanced photocatalytic activity. As a result, a significant high apparent quantum yield (AQY) with highest value of 10.2% was obtained for our photocatalyst OLHP/S,N-GQD10.
