Visible light-driven simultaneous H2 production by water splitting coupled with selective oxidation of HMF to DFF catalyzed by porous carbon nitride

Simultaneous H₂ evolution and biomass valorization under visible light. Simultaneous production of H₂ at a rate of 36 μmol h⁻¹ m⁻² and 38.4% DFF yield (>99% selectivity) after 48 h.
