Molecular structure and photosynthesis
Using polymeric carbon nitride to photosynthesize hydrogen peroxide requires both effective light absorption and charge transport. A collaborative study involving group members constructs C–C-linked benzene–heptazine molecular junctions within carbon nitride through thermal ring-opening isomerization of benzoguanamine, examining how this molecular structure affects the reaction.
Experiments and theoretical analysis show that the junction extends the conjugated system and improves light absorption. Its donor–acceptor structure also promotes charge separation. The paper examines a dual-pathway mechanism for hydrogen peroxide synthesis and evaluates catalytic performance in both an isopropanol/water mixture and pure water.
