Single-Step Synthesized Functionalized Copper Carboxylate Framework Meshes as Hierarchical Catalysts for Enhanced Reduction of Nitrogen-Containing Phenolic Contaminants

Nitrogen-containing phenolic contaminants (NCPCs) represent typical pollutants of industrial wastewaters. As catalytic reduction NCPCs is a useful technique and Cu an efficient metal catalyst, Cu-carboxylate frameworks (CuCF) are favorable materials. However, they in powder form, making them difficult to use; thus, this study, CuCF was grown on macroscale supports. Herein, we present facile approach develop such composite by directly using mesh grow the through single-step electrochemical synthesis method, forming (CFM). CFM could be further modified afford with amines (NH2) (CFNM), carboxylates (COOH) (CFCM). These meshes compared investigate how their physical chemical characteristics influenced behaviors for reduction/hydrogenation NPCPs, including nitrophenols (NPs) dyes. Their nanostructures surface properties influence reactions. In particular, CFCM appears most catalyzing 4-NP, much higher rate constant. also shows significantly lower Ea (28.1 kJ/mol). employed many consecutive cycles, as well convenient filtration-type 4-NP reduction. can decolorization methylene blue methyl orange dyes via hydrogenation.
