The　nature　of　porous　support　(mesoporous　Al2O3　and　MgO　(denoted　as　meso-Al2O3　and　meso-MgO,　respectively)　and　microporous　HZSM-5)　on　catalytic　performance　of　the　bimetallic　RuCo　nanoparticles　(NPs)　was　investigated　for　the　oxidation　of　1,2-dichloroethane　(1,2-DCE).　Redox　and　acid　properties　and　reaction　intermediates　of　the　samples　were　measured　by　means　of　various　techniques.　The　RuO2　species　were　dominantly　present　in　the　supported　bimetallic　samples,　and　Co　doping　could　increase　the　length　of　the　Ru-O　bond.　Compared　with　RuCo/　meso-MgO　and　RuCo/meso-Al2O3,　RuCo/HZSM-5　exhibited　the　highest　catalytic　activity　(T-90%　=281　degrees　C,　TOFNoble　metal　=　3.6　x　10(-3)　s(-1),　reaction　rate　at　270　;degrees　C　=　18.7　mu　mol/(g(Noble　metal)　s),　and　apparent　activation　energy　=36　kJ/mol　at　SV　=　20,000　mL/(g　h))　and　the　best　Cl-resistant　performance,　which　was　associated　with　its　strong　redox　ability,　suitable　acidity,　good　1,2-DCE　adsorption　capacity,　highly　dispersed　RuCo　NPs,　and　strong　interaction　between　RuCo　NPs　and　HZSM-5.　Loading　of　RuCo　NPs　on　the　support　could　suppress　the　formation　of　C2H3Cl　and　improve　the　Cl-resistant　performance.　Over　the　RuCo/HZSM-5　sample,　the　partial　deactivation　induced　by　water　vapor　or　HCl　addition　was　reversible,　while　that　induced　by　SO2　introduction　was　irreversible.　Based　on　the　characterization　results,　we　believe　that　the　oxidation　of　1,2-DCE　over　RuCo/meso-Al2O3,　RuCo/　meso-MgO　or　RuCo/HZSM-5　might　take　place　concurrently　via　the　Langmuir-Hinshelwood　and　Mars-van　Krevelen　mechanisms.　This　work　can　provide　a　strategy　to　develop　the　efficient　catalysts　with　low　Cl-containing　by-products　formation,　high　CO2　selectivity,　and　good　Cl-resistance　in　the　oxidative　removal　of　Cl-VOCs　under　the　practical　conditions.
