Sustainable electro-Fenton simultaneous reduction of Cr (VI) and degradation of organic pollutants via dual-site porous carbon cathode driving uncoordinated molybdenum sites conversion

•A novel sustainable electro-Fenton system is successfully constructed.•NPC-D/MoS2 NA can simultaneously remove Cr (VI) and contaminants.•Dual-site NPC-D cathode has high selectivity of 2e− ORR for H2O2 production.•Electric field-driven MoVI/MoIV conversion rapidly promotes the redox processes.•The...
