Nano-noble　metal　materials　loaded　metal　oxide　greatly　reduce　application　costs,　improve　catalytic　performance　and　sensing　efficiency　compared　with　oxide　substrates.　A　simple　and　efficient　load　method　plays　an　important　role　in　promoting　its　commercialization.　Nano-tungsten　oxide　is　a　kind　of　excellent　gas　sensing　materials　and　it　had　been　widely　used.　Noble　metal　loading　can　form　abundant　active　centers　on　the　surface　of　tungsten　oxide　and　become　an　effective　way　to　improve　its　gas　detecting　performance.　The　complexity　and　high　cost　of　the　loading　methods　hinder　the　its　application　and　commercialization　on　supported　catalysts.　In　this　paper,　Au/WO2.6　composites　with　high　loading　rate　were　prepared　on　layered　tungsten　oxide　nano-flakes　by　a　simple　and　low-cost　method.　The　gas　sensitivity　of　WO2.6　to　ethanol　and　formaldehyde　without　Au　and　with　Au　were　tested.　The　results　show　that　the　loading　rate　is　the　highest　after　reaction　for　24　hours.　The　gas　sensitivity　of　Au　loaded　WO2.6　is　significantly　improved.　The　sensitive　mechanism　on　Au/WO2.6　composite　were　discussed　in　our　work.　©　Published　under　licence　by　IOP　Publishing　Ltd.
