Transition metal oxides have been recognized as promising catalysts for the activation of peroxymonosulfate (PMS), while underlying mechanism involved in relevant processes remains obscure. Here, we identify reactive species generated CuFe2O4/PMS process and illustrate their roles degradation aromatic compounds with different substituent groups (i.e., phenol benzoic acid). Experimental results showed that free radicals sulfate (SO4•−) hydroxyl (HO•), surface Cu(III) species, singlet oxygen (1O2) coexist process. The are mainly responsible oxidation electron-withdrawing group acid), is major removal electron-donating phenol). In addition, 1O2 plays a negligible role both acid phenol. This study enhances fundamental understanding transition oxides-catalyzed PMS

Abstract In heterogeneous persulfate‐catalyzed oxidation systems, the mechanism underlying crystal plane effects of catalyst on selective conversion reactive oxygen species (ROS) remains ambiguous. this study, nano‐Co 3 O 4 catalysts with varying crystallinity and exposure levels (111) planes are prepared via a hydrothermal method. Compared to low crystalline catalysts, high predominantly expose containing higher concentrations Co 2+ vacancies (Ov), resulting in an increase degradation efficiency p‐nitrobenzaldehyde (4‐NBA) from 74.5% 100%. Radical quenching experiments EPR characterization reveal that 4‐NBA occurs through radical pathway, quantification radicals demonstrates increasing effectively promote yield (C SO4•‐ 18.2 172.8 µ m C •OH 1 58.9 ). Furthermore, XPS DFT calculations indicate possesses more Ov active sites planes. The presence not only facilitates adsorption PMS molecules but also enhances electron transfer PMS, leading directed formation efficient transformation radicals. This study presents novel strategy for promoting persulfate‐activated systems.
