Preparation of SnO2/SiO2 nanocomposites by sol-gel method for enhancing the gas sensing performance to triethylamine

SnO2 has become one of the hot materials for research at this stage due to the advantages of simple preparation, low cost and stable properties. In this study, SnO2/SiO2 nanocomposites were prepared by the sol-gel method. The structure, properties and morphology of the SnO2 nanoparticles were determined by HRTEM, SEM, XPS FTIR and XRD characterization. Compared with the pure SnO2 material, the SnO2/SiO2 composite has superior gas sensing...
