A dual-interface modulated photocatalytic H2O2 generation system was constructed, integrating a self-floating gas-liquid-solid triphase reaction interface and a Z-scheme catalyst heterointerface. By incorporating hydrophilic black phosphorus (BP) nanosheets to finely regulate the wettability, visible light absorption, and charge transfer ability of a superhydrophobic vinylene-linked HNT-COF, a BP/HNT-COF heterojunction was formed, achieving a high H2O2 production rate of 352.99 µmol g-1 h-1 using air as the O2 source without any sacrificial agents.
