Carbon-framework-encapsulated CoMn2O4 spinel derived from electrospun nanofiber coupling via the photothermal approach reinforces PMS activation to eliminate 2,4-dichlorophenol

Multiple coupling of metal–carbon interaction, dual-metal redox cycles, and photothermal property can be enabled in the carbon framework hybridized Co 2 Mn 2 O 4 composite catalyst by electrospun approach, rendering improved activation efficiency of PMS.
