Abstract

•A heterogeneous photo-Fenton system without external H2O2 supplement was developed.•An efficient all-solid-state Z-scheme α-Fe2O3/g-C3N4 was fabricated.•The dominant oxidative species of ·OH was generated from self-produced H2O2 decomposition.•96% of organic pollutant removal was achieved after 90 min.•A new reasonable photo-Fenton mechanism was proposed.
