The　elimination　of　volatile　organic　compounds　(VOCs)　emitted　from　the　process　of　industry　production　is　of　great　significance　to　improve　the　atmospheric　environment.　Herein　the　catalytic　oxidation　of　the　toluene　and　iso-hexane　mixture,　as　the　typical　components　from　furniture　paint　industry,　and　the　enhancement　in　the　catalytic　stability　for　toluene　oxidation　were　investigated　in　detail.　The　formation　rate　of　active　oxygen　species　was　very　important　for　the　development　of　the　catalyst　with　high　catalytic　stability.　Compared　with　the　Pt/M　catalyst,　the　Pt-Cu/M　catalyst　owned　stronger　ability　of　VOCs　adsorption　and　gaseous　oxygen　activation　by　introducing　additional　sites　for　activating　O2.　The　Langmuir-Hinshelwood　(adsorbed　oxygen)　and　Mars-van　Krevelen　(lattice　oxygen)　mechanism　existed　in　toluene　oxidation　over　the　present　Pt/M　and　Pt-Cu/M　catalysts,　respectively.　The　change　in　the　involved　active　oxygen　species　during　toluene　oxidation　was　resulted　from　the　Pt-Cu　alloy　structure.　In　addition　to　the　adsorption　of　O2,　a　part　of　active　lattice　oxygen　species　can　also　be　replenished　by　the　migration　of　bulk　lattice　oxygen　over　Pt-Cu/M.　With　a　rise　in　the　reaction　temperature,　weakly　adsorbed　iso-　hexane　could　be　timely　reacted　with　the　more　active　lattice　oxygen　species　to　keep　the　catalytic　stability　over　the　Pt/M　and　Pt-Cu/M　catalysts.　Generally,　we　not　only　prepared　a　promising　material　for　the　catalytic　removal　of　VOCs　from　the　furniture　paint　industry,　but　also　provided　a　new　strategy　for　the　generation　of　active　oxygen　species,　making　the　catalyst　exhibit　high　catalytic　oxidation　stability.
