Fabrication of a ZnFe2O4@Co/Ni-MOF nanocomposite and photocatalytic degradation study of azo dyes

This study addresses the critical issue of removing organic pollutants from water, focusing on the photocatalytic degradation of Congo red (CR) dye using a novel ZnFe 2 O 4 @Co–Ni metal–organic framework (MOF) nanocomposite (ZFCNM).
