Oxygen vacancy (O) engineering is a widely accepted effective strategy to manipulate the catalytic activity for volatile organic compounds (VOCs) abatement. Herein, we report the oxygen vacancy-mediated Ag/CeO-CoO catalyst to boost benzene combustion. The incorporation of Ag species in Ag/CeO-CoO induces the predominately exposed surface Co sites and structural distortion of CoO as well as rich oxygen vacancy owing to the improved interfacial electron transfer, which promote the adsorption of benzene and the dissociation of oxygen.
