The　long-standing　contradiction　between　low-temperature　activity　and　high-temperature　stability　is　one　of　the　difficulties　in　catalytic　combustion　of　low-concentration　methane.　The　traditional　Pd-CeO2　catalyst　system　has　been　applied　to　the　oxidation　of　methane　with　low　concentrations.　However,　the　problem　of　sintering　at　high　temperatures　still　exists.　In　this　work,　we　prepared　the　Pt-modified　Pd-CeO2　nanowires　(NW)　sample　(in　which　the　actual　Pt,　Pd,　and　Ce　contents　were　0.12,　0.86,　and　9.8　wt%,　respectively)　using　the　one-pot　reverse-micelle　emulsion　method.　It　was　found　that　Pt-Pd-CeO2NW@SiO2　showed　the　highest　low-temperature　catalytic　activity　at　a　space　velocity　of　20,000　mL/(g　h)　and　the　best　water　resistance　and　high-temperature　stability　in　the　combustion　of　methane.　The　T50　%　and　T90　%　(the　temperatures　for　achieving　methane　conversions　of　50　and　90　%)　were　298　and　342　degrees　C,　respectively,　methane　reaction　rate　at　270　degrees　C　was　0.49　mu　mol/(gcat　s),　and　turnover　frequency　(TOF)　at　270　degrees　C　was　0.198　s-1　over　Pt-Pd-CeO2NW@SiO2;　whereas　over　Pd-CeO2NW@SiO2　(in　which　the　actual　Pd　and　Ce　contents　were　0.82　and　10.6　wt%,　respectively),　the　T50　%　and　T90　%　were　360　and　420　degrees　C,　respectively,　methane　reaction　rate　at　270　degrees　C　was　0.074　mu　mol/(gcat　s),　and　TOF　at　270　degrees　C　was　0.032　s-　1.　The　introduction　of　the　highly　dispersed　Pt　to　Pd-CeO2NW@SiO2　could　effectively　increase　the　PdOx　sites　of　unsaturated　coordination　through　the　electron-donating　interaction　of　the　Pt　with　PdO,　which　played　an　important　role　in　activating　the　C-H　bonds　in　methane.　In　addition,　the　unique　structure　of　encapsulation　also　rendered　the　Pt-Pd-CeO2NW@SiO2　sample　to　possess　good　water　resistance　and　thermal　stability　in　methane　combustion.　We　are　sure　that　the　present　work　provides　a　possibility　for　developing　the　catalysts　with　stable　catalytic　and　water-resistant　performance　at　low　and　high　temperatures　in　the　combustion　of　methane.
