主 题：Phenol degradation Electrocatalytic oxidation Three-dimensional electrochemical Particle electrode Advanced oxidation
摘 要：High-concentration phenol wastewater is pollutant of concern that pose significant risks to human health and the ***-dimensional electrocatalytic oxidation is one of the most promising wastewater treatment technologies because of its high treatment efficiency,low energy consumption and low secondary ***-cost and higher-performance particles still faces great *** this work,metal oxide particle electrodes were prepared using granular activated carbon(GAC)as a substrate to study the degradation of phenol by three-dimensional electrocatalytic *** particle electrodes loaded with different monometallic oxides(Mn,Fe,Co,Ce)and bimetallic oxides(Fe and Ce)were prepared by the impregnation *** effectiveness of the particle electrodes in degrading phenol was greatly improved after active components *** all monometallic oxide particle electrodes,the concentration degradation efficiency was in the order of Ce/GACCo/GACMn/GACFe/GAC,and the COD degradation efficiency was Ce/GACFe/GACCo/GACMn/*** optimizing the loading metal type and loading amount,it was found that the 1.1%Fe-2.7%Ce/GAC particle electrode perform the best,with a phenol degradation efficiency of 95.48%,a COD degradation rate of 94.35%,an energy consumption of 0.75 kW·h·kg^(-1)*** lower-cost and higher-performance particle highlights a reliable route for solving the problem of particle electrode materials limiting the efficient treatment of phenol-containing wastewater.
