Manganese　oxide　supported　Pt　single　atoms　(Pt-1/MnOx)　are　prepared　by　the　molten　salt　method.　Catalytic　oxidation　of　toluene　and　iso-hexane,　typical　emissions　from　furniture　paints　industry,　is　tested.　Pt-1/MnOx　shows　poor　and　high　catalytic　stability　for　toluene　and　iso-hexane　oxidation,　respectively.　Enhancement　in　the　catalytic　stability　for　toluene　oxidation　is　observed　after　the　hydrogen　reduction　treatment　of　Pt-1/MnOx　at　200　degrees　C.　The　hydrogen　treated　catalyst　possesses　the　weaker　Mn-O　bonds　and　lower　coordination　number　of　Pt-O,　with　superior　mobility　of　lattice　oxygen　and　appropriate　toluene　adsorption.　Balancing　lattice　oxygen　mobility　and　volatile　organic　compounds　adsorption　is　important　for　the　catalytic　stability　of　Pt-1/MnOx.　For　the　oxidation　of　toluene　and　iso-hexane　mixture,　owing　to　the　competitive　adsorption,　iso-hexane　oxidation　is　greatly　inhibited,　while　toluene　oxidation　is　not　influenced.　The　present　Pt-1/MnOx　catalyst　holds　promising　prospect　in　furniture　paints　industry　applications　because　of　high　catalytic　stability　and　water　resistance　ability.
