Featured　ApplicationThis　work　supplies　a　systematical　comparison　study　on　various　typical　noble　metal　catalysts　with　an　exploration　of　the　potential　for　CVOC　destruction,　which　would　supply　an　overall　view　of　universal　applicability　for　the　practical　operation　of　noble　metals.Understanding　the　reaction　path　and　mechanism　of　chlorinated　volatile　organic　compound　(CVOC)　destruction　is　important　for　designing　efficient　catalysts,　especially　for　the　application　of　noble　metal-based　materials.　Herein,　several　typical　noble　metals,　Ru,　Rh,　Pt,　Pd,　Au,　and　Ir,　supported　on　gamma-Al2O3　catalysts　were　synthesized　by　the　hydrazine　hydrate　reduction　method　for　1,2-dichloroethane　(1,2-DCE)　elimination.　Various　character　measurements　were　conducted,　and　the　results　suggest　that　the　high-valence　state　of　noble　metals　is　beneficial　for　the　1,2-DCE　reaction　as　it　enables　the　enhancement　of　the　mobility　of　the　surficial　active　oxygen　species　of　catalysts.　Among　the　noble　metals,　Ru/gamma-Al2O3　expresses　superior　catalytic　reactivity,　with　a　90%　pollutant　conversion　rate　at　337　&　DEG;C,　and　competitive　CO2　selectivity,　99.15%　at　the　temperature　of　total　oxidation.　The　distribution　of　by-products　and　the　degradation　routes　were　analyzed　online　by　GC-ECD　and　in　situ　diffuse　reflectance　infrared　spectroscopy,　which　may　provide　helpful　insight　for　the　future　application　of　noble　metal-based　catalysts　for　CVOC　elimination　in　industrial　fields.
