Copper-decorated iron oxide nanoparticles highly dispersed on coal-based activated carbons: a recoverable catalyst for the reduction of 4-nitrophenol, Congo red, and Rhodamine B

Abstract

A copper-decorated iron oxide/AC catalyst was fabricated by a facile co-precipitation method combined, which demonstrates high catalytic performance in the hydrogenation reduction of 4-nitrophenol (4-NP), Rhodamine B (RhB) and Congo red (CR).
