Significance Heterogeneous peroxymonosulfate (PMS)–based advanced oxidation process (AOP) has been extensively tested for water purification, but its application feasibility at large scale has not been validated. Here, we develop a facile coprecipitation method for the scalable production (∼10 kg) of the nonstoichiometric Cu-Fe-Mn spinel oxide (CuFeMnO) catalyst with a great PMS-activation capacity. The mechanisms for the robust PMS-catalytic ability of this catalyst are elucidated with a suite of experiments and theoretical calculations. Furthermore, the application feasibility of applying the CuFeMnO-PMS AOP for water treatment at both bench and pilot scales is demonstrated. This work validates the great potential of scalable preparation for the nonstoichiometric CuFeMnO catalyst and provides a conceptual advance to design robust and practical PMS-based catalytic systems for water purification.
