Since　the　Pt-based　catalysts　often　suffer　severe　deactivation　by　chlorine,　development　of　a　catalyst　with　good　activity　and　chlorine-resistant　ability　is　of　importance　in　effectively　controlling　emissions　of　(chlorinated)　volatile　organic　compounds　((C)VOCs).　In　this　work,　we　prepared　the　Al2O3-supported　bimetallic　catalysts　with　narrow　metal　particle　size　distributions　and　their　application　in　benzene　oxidation.　It　is　found　that　PtW/Al2O3　showed　the　highest　catalytic　activity　and　the　lowest　activation　energy.　The　characterization　results　were　well　correlated　with　the　catalytic　activities,　and　a　Pt-MOx　(M　=　W,　Mo)　bimetallic　synergistic　effect　was　proposed.　In　situ　FTIR　studies　reveal　that　the　transformation　from　phenol　to　benzoquinone　was　the　key　step　in　benzene　oxidation　process.　The　influence　of　1,2-dichloroethane　(DCE)　on　catalytic　activity　for　benzene　oxidation　of　the　as-obtained　samples　was　also　examined.　It　is　demonstrated　that　there　was　a　competitive　adsorption　between　benzene　and　DCE　molecules,　and　the　DCE　exerted　an　inhibitive　effect　on　benzene　oxidation.　We　conclude　that　excellent　catalytic　performance　of　the　bimetallic　sample　was　associated　with　its　good　abilities　to　adsorb　and　activate　benzene　on　small　ensembles　of　the　MOx　in　proximity　contact　with　Pt　as　well　as　the　strong　interaction　between　the　highly　dispersed　metallic　Pt　species　and　the　MOx　clusters　(which　led　to　enhancement　in　antideactivation　of　the　Pt　species　under　the　oxygen-rich　and　Cl-containing　reaction　conditions).　We　are　sure　that　the　present　work　can　provide　an　idea　for　understanding　the　nature　of　bimetallic　active　sites　and　rationally　designing　the　efficient　bimetallic　catalysts　for　the　oxidative　removal　of　VOCs.
