MOF-derived CoN/N-C@SiO2 yolk-shell nanoreactor with dual active sites for highly efficient catalytic advanced oxidation processes-dataset

The CoN yolks (∼50–70 nm) as active sites were encapsulated by the hydrophilic SiO2 shells (∼30 nm), and some small dots (∼5–10 nm) was sandwiched between void spaces. In-situ formation of N-doped carbon layer not only served as active sites but also improved electron transfer.

The yolk-shell nanoreactors were applied for catalytic tetracycline (TC) degradation by activation of peroxymonosulfate (PMS), and in the optimal case, it degraded >∼95% TC within 30 min in a wide pH value range of 2.02–9.94. The quenching experiments and EPR measurements further revealed that synergistic effect of the radicals and nonradical in PMS activation, O2−, OH, SO4− and 1O2 were involved in TC degradation.
