Metal Borides as Excellent Co-Catalysts for Boosted and Long-Lasting Fenton-like Reaction: Dual Co-Catalytic Centers of Metal and Boron

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(33), P. 12534 - 12545

The continuous electron supply for oxidant decomposition-induced reactive oxygen species (ROS) generation is the main contributor long-standing micropollutant oxidation in iron-based advanced processes (AOPs). Herein, as a new class of co-catalysts, metal borides with dual active sites and preeminent conductive performance can effectively overcome inherent drawback Fenton-like reactions by steadily donating electrons to inactive Fe(III). Among borides, tungsten boride (WB) exhibits significant co-catalytic run ahead common heterogeneous co-catalysts exceptionally high stability. Based on qualitative semi-quantitative tests, hydroxyl radical, sulfate iron(IV)-oxo complex are all produced WB/Fe(III)/PDS system Fe(IV)-induced methyl phenyl sulfoxide decomposition up 72%. Moreover, production efficiency ROS relative proportions radical nonradical pathways change various experimental conditions (dosages PDS, WB, solution pH) water matrices. rate-determining step Fe(II) regeneration greatly accelerated resulting from synergetic effect between exposed metallic nonmetallic boron reductive properties WB. In addition, self-dissolution surface oxide leads renovated sustainable Fe(III) reduction long-term operations. Our discovery provides an efficient strategy field enhanced AOPs remediation.
