The　improvement　of　Fe(III)/Fe(II)　conversion　efficiency　and　facilitation　for　recycling　of　Fe-based　catalyst　have　dual　economic　and　green　benefits　in　the　field　of　photo-Fenton-like　for　wastewater　treatment.　To　achieve　those　purposes,　we　have　designed　and　fabricated　an　S-scheme　catalyst　by　in-situ　growing　magnetic　sodium　ferric　silicate/ferroferric　oxide-ferric　oxide　(SFS/M-FO)　heterojunction.　Our　results　demonstrated　the　mechanism　of　heterogeneous　interface　formation　and　S-scheme　charge　transportation　between　NaFeSi2O6　and　alpha-Fe2O3　in　the　composite.　Meanwhile,　the　semi-coherent　interface　in　heterojunction　could　effectively　reduce　the　charge　transfer　resistance.　The　incorporation　of　magnetic　ferroferric　oxide　(Fe3O4)　not　only　ensured　high　recoverability　of　the　catalyst,　but　also　facilitated　charge　transfer　and　improved　light　absorption　capacity.　The　improved　catalytic　activity　was　derived　from　the　combination　of　the　S-scheme　NaFeSi2O6/alpha-Fe2O3　heterojunction　and　Fe3O4　elec-tronic　conductor.　Therefore,　the　SFS/M-FO　composite　showed　excellent　tetracycline　removal　rate　of　91.8%　within　50　min　in　the　photo-Fenton-like　reaction.　The　ternary　composite　also　held　excellent　performance,　reus-ability　and　structural　stability.　The　produced　intermediates　and　three　degradation　pathways　of　tetracycline　were　identified　by　liquid　chromatograph-mass　spectrometer.　This　study　offers　a　convenient　way　for　combining　high　performance　and　magnetical　retrievability　by　in-situ　growth　method　for　wastewater　treatment.
