Waste plastic has imposed significant burdens on marine ecosystems. Converting into high-value products via photocatalysis is an emerging and promising approach, but its low activity product selectivity pose great challenges. Herein, we report a carbon nitride-anchored atomically dispersed Pt-B dual-site catalyst (Pt SA/BCN100) for the photoreforming of polylactic acid (PLA) chemicals H2 in seawater. Experiments DFT calculations reveal that significantly enhanced charge transfer occurs between Pt site B site, hole-rich can selectively trigger activation cleavage C-H C-C bonds PLA to form acetic (AA), while electron-rich drives reduction H protons H2. As result, SA/BCN100 exhibits high evolution rate 993 μmol gcatal-1 h-1 AA production 300 with over 98%. We also demonstrate direct g-scale real-world wastes concentrations microplastics natural Techno-economic analysis environmental assessment show this catalytic system reduce emissions potential commercial value.
