文摘

Herein, we describe a strategy for fabricating ordered mesoporous In2O3-reduced graphene oxide (rGO) nanocomposite through ultrasonic mixing, where ordered mesoporous In2O3 nanoparticles are synthesized via the nanocasting route by using mesoporous silica as a hard template, which possess ordered mesostructure with a large surface area of 81?m2 g?, and rGO nanosheets are synthesized from graphite via graphene oxide (GO) as intermediate. After coupled with rGO, mesoporous In2O3 could maintain its ordered mesostructure. We subsequently investigate the gas-sensing properties of all the In2O3 specimens with or without rGO for different gases. The results exhibit the ordered mesoporous In2O3-rGO nanocomposite possesses significantly enhanced response to ethanol even at low concentration levels, superior over pure mesoporous In2O3 nanoparticles. Similar strategy could be extended to other ordered mesoporous metal oxide–rGO nanocomposite for improving the gas-sensing property.
