摘要

•Magnetically separable MnFe2O4 nanoparticles are synthesized onto SnS2 microflowers to fabricate a Z-scheme MnFe2O4@SnS2 heterojunction.•The MnFe2O4@SnS2-2 composite photocatalyzes 92.08 % degradation of MB at 120 min under pH = 9 and 1.5 mL H2O2.•MnFe2O4@SnS2 heterojunction possesses the widened band gap and weakened luminescence.•OH is the main active specie in photo-Fenton degradation.
