dc.description.abstractIn this work, we developed a hierarchically multi-faceted ordered porous carbon crystal (HOPC) for generating a favorable chemical microenvironment to intensify both Fe3+ binding and H2O2 utilization efficiency. The confined pore space and surface functionality enable •OH and micropollutants to be concentrated in the pores, thus significantly accelerating pollutant degradation kinetics (0.034 min− 1 ) with reduced chemical consumption (0.081 mM H2O2). Theoretical calculations and in-situ characterizations reveal that both C––O and pyrrolic N act as active sites bridging Fe3+, facilitating the transfer of outermost e− from the p-orbital of active sites (O and N) to the d-orbital of iron, effectively reducing Fe3+ to Fe2+ and enhancing the open-circuit potential of HOPC-Fe3+ complexes, as well as facilitating e− extraction from H2O2. For the first time, H2O2 was unveiled to be both an electron donor and acceptor to cooperate with the iron redox cycle for sustainable •OH generation toward fast pollutant decontamination.
