Heterogeneous sulfate radical-mediated benzotriazole oxidation by ferrospinel nanoparticles catalyzed peroxymonosulfate: A catalyst for environmental remediation

The sulfate radical-based advanced oxidation process has been widely investigated via peroxymonosulfate (PMS) activation in recent years, in which the development of catalysts with high efficiency and stability is crucial. The current work prepared a series of magnetic nanoparticles, including CuFe2...
