Electrochemical treatment is a promising alternative for the treatment of phenolic waste water. Electrocatalytic oxidation of phenol was investigated in the presence of ZnO

CuO

Fe2O3 supported on carbon aerogel as particle electro des. Special attention was paid to experimentally probe the performance of pheno l removal in the process of repeated batch runs. The experimental results showed that

at the same conditions

ZnO dispersed carbon aerogel

as particle electro des could remove phenol-containing wastewater much more efficiently than other p article electrodes.
