AI Technical Summary
Existing photocatalytic hydrogen peroxide synthesis technologies suffer from kinetic mismatch issues, resulting in low generation efficiency, poor selectivity, and increased side reactions. The proton transport pathway lacks continuity and directionality, electron and proton supply cannot be synchronously and synergistically regulated, and the oxidation and reduction half-reactions lack a closed-loop matching mechanism.
Using carboxyl-functionalized hypercrosslinked conjugated polymers as photocatalysts, a three-dimensional conjugated network structure was constructed by mixing tetraphenylporphyrin with π-conjugated dianhydride monomers, introducing carboxyl functional units to form a continuous proton transport pathway, and combining alcohols as external proton-electron donors to establish a two-phase closed-loop proton-coupled electron transfer system.
It achieves a high rate of hydrogen peroxide production and maintains good catalytic performance after multiple cycles. It simplifies operation, provides mild reaction conditions, improves light energy utilization efficiency and production selectivity, and suppresses side reactions.
