NOVELTY - Preparing sub-stoichiometric titanium oxide (Ti4O7) anode loaded with graphene nanoparticles comprises mixing titanium oxide powder, graphene nanoparticles and cerium dioxide powder, ball milling to obtain mixed powder, and processing discharge plasma sintering at high temperature and high pressure to obtain anode. USE - The anode is useful for recovering 1,4 dioxane-contaminated groundwater. ADVANTAGE - The method improves the catalytic activity of anode, increases the number of surface active sites, improves the output of hydroxy radical, reduces the charge transfer internal resistance and has the ability of degrading 1,4-dioxane similar to boron-doped diamond electrode (BDD).
