Abstract

Nano composite AC (active carbon) supported Cu/Nd catalyst was prepared by sol-gel method using Cu(NO₃)₂ and Nd(NO₃)₃ as active components. Electro-catalytic oxidation of phenolic wastewater was performed by using a stainless steel wire basket filled with Cu/Nd-AC catalyst as anode, and air diffusion electrode as cathode (ADE). The catalytic activity of the prepared catalyst was evaluated by of COD (chemical oxygen demand) and phenol removal rates of the wastewater. The optimum parameters were found to be as follows: Cu/Nd-AC catalyst dosage = 5g/L, solution pH = 3, and electrolysis current density = 400mA/dm². In this case, the COD and phenol removal rates could reach 98.32% and 99.59%, respectively, after 1h degradation for a phenol solution of 504mg/L concentration.

Key words： sol-gel method supported catalyst electro-catalytic oxidation phenolic wastewater air diffusion electrode
