Preparation, characterization and sensing property of MoO3-SnO2 nanocomposites

INTRODUCTION The detection to toxic gas emissions is extremely important for human safety and environmental protection 1. Metal oxides, such as SnO2, ZnO, Fe2O3 and WO3, have been used to obtain inexpensive and reliable semiconductor sensors with good sensitivity and selectivity to NO2 gas. Among various semiconducting oxides, SnO2 has been widely used as gas sensors, electrode materials, catalyst supports and solar cells, etc. 2, 3. Especially, SnO2 has been the most popular sensor material so far investigated and used in practice, and a great deal of research efforts have been exerted to improve the gas-sensing properties of SnO2-based sensors. The grain size of metal oxide used, additives and sensor structure are effect the gas-sensing properties. However, these sensors based on SnO2 or other single-component oxides are lack of thermal stability and selectivity.
