Nitrogen　oxides　(NOx)　and　chlorobenzene　(CB)　released　during　waste　incineration　and　iron　ore　sintering　pose　significant　threats　to　both　the　atmosphere　and　human　health,　necessitating　effective　control　measures.　Vanadium-based　catalysts　are　commonly　employed　for　the　simultaneous　control　of　NOx　and　CB;　however,　their　catalytic　performance　requires　further　enhancement.　In　this　study,　the　NH3-SCR　activity　and　CB　catalytic　oxidation　(CBCO)　activity　were　significantly　enhanced　by　doping　the　V10W/Ti　catalyst　with　Ce.　During　the　multi-pollutant　control　(MPC)　reaction,　the　optimized　15CeV10W/Ti　catalyst　demonstrated　NOx　conversion　approaching　100%　and　N2　selectivity　exceeding　95%　at　temperatures　between　210　and　450　°C.　Additionally,　it　achieved　CB　conversion　nearing　100%　and　CO2　selectivity　above　80%　at　temperatures　above　350　°C.　These　results　were　markedly　superior　to　those　of　the　conventional　commercial　1%V2O5–10%WO3/TiO2　catalyst.　Characterization　studies　indicated　that　the　15CeV10W/Ti　catalyst　possessed　improved　redox　performance　and　more　acidic　sites.　In　the　MPC　reaction,　the　declined　CBCO　activity,　compared　to　the　CB　separate　oxidation,　can　be　attributed　primarily　to　the　competitive　adsorption　of　NH3　with　CB.　Conversely,　the　observed　decrease　in　NOx　conversion　at　lower　temperatures　was　primarily　due　to　the　suppression　of　the　oxidation　of　NO　to　NO2　by　CB.　©　2024　by　the　authors.
