Core-shell Zn/Co MOFs derived Co3O4/CNTs as an efficient magnetic heterogeneous catalyst for persulfate activation and oxytetracycline degradation

Herein, we report a facile and straight strategy to synthesize a highly efficient and recyclable heterogeneous catalyst through a pyrolysis–oxidation of core–shell Zn/Co metal organic frameworks (MOFs). The selected Zn MOF crystals was used as a single precursor to form a nanostructured hollow framework through the evaporation of Zn at high pyrolysis temperature. Meanwhile, the numerous carbon nanotubes (CNTs) was formed on the surface of a...
