%X Different from the traditional supported cobalt catalyst, a dissolution regeneration strategy of multistage hollow cobalt hydrosilicate nanospheres (csh-80) which can maximize the cobalt active site on the basis of unit mass is proposed. Due to the unique design and careful nanostructure, the cobalt active center can be evenly dispersed into the structural catalyst to maximize the exposure of the cobalt center to the reaction. In the process of activated peroxymonosulfate (PMS) degrading organic pollutants, csh-80 shows excellent catalytic performance, good physicochemical stability and long-term durability. The efficiency of csh-80 is 1.9 ~ 3.1 times higher than that of traditional supported cobalt catalyst. The turnover frequency of csh-80 in organic oxidation is 2.0 ~ 3.2 times higher than that of traditional supported cobalt catalyst. The effects of reaction parameters on pollutant degradation were systematically investigated. The mechanism of catalytic oxidation was further clarified by quenching test, electron paramagnetic resonance and photoluminescence. The design concept of this study will provide new opportunities for the development of high-performance cobalt based heterogeneous catalysts in environmental remediation in the future.This data set was produced in laboratory experiments, and its properties were characterized by XRD, XPS, IR and bet. The morphology was characterized by TEM. The data set includes 11 groups and 31502 pieces of data. The data set is completely open and shared.
