|a The efficient activation of the O-O band in persulfate (PDS) with high energy was important and could be achieved by the interface engineering of catalysts. It was discovered that the robust bisphenol A (BPA) degradation could be achieved in the presence of PDS via different mechanisms with steel-wool-shaped Cu-Co3O4 composites obtained via in-situ hydrolysis of cobalt and copper nitrate with zeolitic imidazolate framework-67 after calcination. The calcination temperature at 483 K resulted in abundant oxygen vacancies in Cu-Co3O4 with the amorphous structure, which displayed about a 25-fold higher degradation rate constant (k = 0.385 min-1) than that (0.015 min-1) of Co3O4 for BPA disposal with PDS, possibly via forming the surface-activated complex process. The higher temperature (583 K) treated Cu-Co3O4 could also lead to the fast BPA degradation with the k of 0.670 min-1, which was more than 160-fold higher than the referenced Co3O4 and experienced the radical and nonradical processes, including the HO•, SO4•-, O2•-, and 1O2 as reactive oxygen species. The above difference was possibly due to the amount of oxygen vacancy, the ratio of metal ions with different oxidation states, and the interaction of Cu-O-Co in the composite
