The ZnO\/Fe<jats:sub>3<\/jats:sub>O<jats:sub>4<\/jats:sub>@carbon spheres exhibited relatively high catalytic degradation properties for AO7 in an aqueous solution. The AO7 degradation reached 93.6% in 15\u00a0min under the conditions: 0.20\u00a0g\/L ZnO\/Fe<jats:sub>3<\/jats:sub>O<jats:sub>4<\/jats:sub>@carbon spheres, 1.25\u00a0mmol\/L PMS, 0.03\u00a0mmol\/L AO7, and initial pH of 4. Findings revealed that higher ZnO\/Fe<jats:sub>3<\/jats:sub>O<jats:sub>4<\/jats:sub>@carbon spheres dose and PMS concentration, lower initial AO7 concentration, and acidic pH favored the AO7 degradation to a certain extent. The mechanisms for the activation of PMS by ZnO\/Fe<jats:sub>3<\/jats:sub>O<jats:sub>4<\/jats:sub>@carbon spheres were proposed based on the results of radical identification tests and structure characterization.
