Metallic nanoparticles for electrocatalytic reduction of halogenated organic compounds: A review

Increasing attention is paid to the degradation of refractory halogenated organic compounds in wastewaters. For this purpose, electrocatalytic reduction process constitutes a promising technology due its high selectivity. Owing their well-controlled structure and specific surface area, nanoparticles have been subject many investigations electrocatalysis. This study presents general review on nanoparticles-modified electrodes achieve reductive dehalogenation. The role electrode support, especially 3-D Carbon metallic porous are first discussed. Then, methods prepare supports included spontaneous deposition and/or electrodeposition summarized commonly used characterization modified also presented. influence material, Ag, Pd, Cu, as representatives, electro-dehalogenation discussed compared. Finally, highlights recent applications these for treatment aqueous solutions.
