Facile green synthetic graphene-based Co-Fe Prussian blue analogues as an activator of peroxymonosulfate for the degradation of levofloxacin hydrochloride.

A kind of Co-Fe Prussian blue analogues (Co-Fe PBAs), cobalt hexacyanoferrate Co[Fe(CN)], and graphene oxide (GO) were combined to synthesize magnetically separable Co-Fe PBAs@rGO nanocomposites through a simple two-step hydrothermal method. The crystalline structure, morphology and textural properties of the Co-Fe PBAs@rGO nanocomposites were characterized. The catalytic performance of the nanocomposites was evaluated by PMS activation, with Levofloxacin Hydrochloride (LVF) as the target contaminant.
