The design of metal-organic framework-derived metal oxides/sulfides is an effective approach for water remediation. A series of Fe-Ce composites (Fe-Ce-S-N) with cluster-like morphology were prepared with prussian blue analogue (PBA) as the precursor in a hydrothermal process. S doping promoted the conversion of Fe(III) to Fe(II), which greatly improved the performance of the Fenton-like reaction. The optimized Fe-Ce-S-N catalyst exhibited superior catalytic activity towards sulfamethoxazole(SMZ) degradation (18.63 mgSMZ gcat.-1 min-1), showing the largest k value (0.1862 min-1), which was 2.1 and 8.1 times higher than that of Fe-Ce-S-H and Fe-Ce-N, respectively. Moreover, the Fe-Ce-S-N catalyst displayed the remarkable reusability, stability and adaptability in Fenton-like systems. Overall, this work provides new insights into extending novel PBA-derived catalysts to significantly improve heterogeneous Fenton-like performances.
