Supported　noble　metal　catalysts　are　highly　effective　for　eliminating　volatile　organic　compounds　(VOCs).　A　catalyst　with　less　noble　metal　loading　is　always　desirable.　Using　a　mixture　of　NaNO3　and　NaF　as　molten　salt,　Fe　(NO3)(3)　and　Pt(NH3)(4)(NO3)(2)　as　metal　precursors,　xPt/Fe2O3　catalysts　(x　=　0-0.3　wt%)　were　fabricated　after　calcination　at　350　degrees　C　for　3　h.　At　space　velocity　of　40,000　mL/(g　h),　0.22　wt%　Pt/Fe2O3　showed　the　best　catalytic　activity,　and　o-xylene　could　be　completely　oxidized　into　CO2　and　H2O　at　225　degrees　C.　Furthermore,　0.22　wt%　Pt/Fe2O3　exhibited　good　stability,　and　high　resistance　to　water　vapor,　CO2,　and　SO2.　We　deduce　that　the　excellent　catalytic　performance　of　0.22　wt%　Pt/Fe2O3　was　associated　with　the　high　dispersion　of　the　Pt　species　and　good　low-temperature　reducibility.　The　possible　reaction　mechanism　of　o-xylene　oxidation　over　0.22　wt%　Pt/Fe2O3　involved　the　adsorption　of　o-xylene　molecules,　partial　decomposition　into　small　organic　intermediates　(e.g.　maleic　anhydride　and　aliphatic　carboxylate　species),　and　total　oxidation　into　CO2　and　H2O.　Due　to　the　high　efficiency,　good　stability,　low　cost,　and　convenient　preparation,　the　present　catalysts　are　promising　for　the　practical　removal　of　VOCs.
