摘要

•High-energy ball-milling was conducted to regulate the surface property of Mn3O4.•Ball-milled Mn3O4 switched 1O2-dominated pathway into electron transfer process.•Electron transfer achieved higher intrinsic activity and PMS utilization.•Electron transfer exhibits practical applicability in water purification.•Mechanical force altered eg occupancy of Mn and contributed to reactive complex.
