The strong adsorption of the exsolved A-site of SrCoO2.52 (SC) perovskite with peroxymonosulfate (PMS) makes the effective activation of PMS challenging. A surface reconstruction strategy has been applied to enhance direct electron transfer from the active B-site to PMS. Thus, an interface architecture of Co3O4 nanoparticles in situ growing on the SC perovskite [SrCoO3−δ@Co3O4 (SCC-2)] was developed, which exhibited enhanced catalytic activity. 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. The formed Co–O metal–oxygen bridge facilitated the electron transfer from the bulk SrCoO3−δ to the Co sites of surface Co3O4, thus enhancing the Co2+/Co3+ redox cycle. Compared with pristine SC, the PMS activation improved by 13.1%, and ENR degradation boosted by 1.23 times for SCC-2. This study can provide guidelines to design superior catalysts by surface reconstruction.
