Promotional effect of nitric acid treatment on co sensing properties of SnO2/MWCNT nanocomposites

In this paper, SnO2/MWCNT nanocomposites with different types of MWCNTs, namely as-received, acid treated and Ag-decorated, were synthesized via a facile method and their CO gas sensing properties were investigated. Microstructure and phase formation of the synthesized composites were studied using FE-SEM and XRD, respectively. Fourier transform infrared spectroscopy (FTIR) was employed to study the functional groups on the surface of MWCNTs...
