![]() ![]() ![]() Compared with pristine SC, the PMS activation improved by 13.1%, and ENR degradation boosted by 1.23 times for SCC-2. The formed Co–O metal–oxygen bridge facilitated the electron transfer from the bulk SrCoO 3− δ to the Co sites of surface Co 3O 4, thus enhancing the Co 2+/Co 3+ redox cycle. It was found that the surface reconstruction process not only transferred the adsorption site of PMS from the Sr to the Co site, but also enhanced the electron transfer ability of SCC-2. ![]() Thus, an interface architecture of Co 3O 4 nanoparticles in situ growing on the SC perovskite was developed, which exhibited enhanced catalytic activity. A surface reconstruction strategy has been applied to enhance direct electron transfer from the active B-site to PMS. The strong adsorption of the exsolved A-site of SrCoO 2.52 (SC) perovskite with peroxymonosulfate (PMS) makes the effective activation of PMS challenging. ![]()
