英文摘要	The development of heterogeneous catalysts of non-noble metal with both high reactivity and activity for the oxygen reduction reaction in catalytic degradation of organic pollutants is a formidable challenge. Here we design an innovative and rational self-propagating combustion method for metallic glasses to synthesize Cu-based composite with high catalytic activity, in which the main compounds of Cu and Cu2O are uniformly dispersed on the surface. The Cu/Cu2O/ZrO2 composite exhibits superior catalytic capability compared to other catalysts. The degradation efficiencies all are approximately 99.8% and the total organic carbon (TOC) removals can be up to more than 60% under optimal reaction conditions. The degradation intermediates and possible decomposition pathways of two dyes for Fenton-like catalytic system were systematically investigated. Importantly, the possible catalytic mechanisms can be proposed catalytic oxidation reaction by activated hydroxyl radicals (center dot OH) and superoxide anion radicals (center dot O-2(-)). These findings provide a new strategy to design efficient composite catalysts for the functional application of wastewater treatment. (C) 2021 Elsevier B.V. All rights reserved.
