摘要：
Nanocomposites based on multiwall carbon nanotubes (MWCNTs) impregnated with manganese oxide MnO2 - (x) and copper oxide CuO are synthesized and studied. The morphology and elemental composition of MWCNT layers and MWCNT/MnO2 - (x) and MWCNT/MnO2 - (x)/CuO nanocomposites are investigated by scanning electron microscopy and X-ray photoelectron spectroscopy. We study the gas-sensing response of the prepared nanocomposites to hydrogen sulfide (H2S) and nitrogen dioxide (NO2). An increase in the conductance observed for the as-grown MWCNTs and the nanocomposites upon NO2 adsorption suggests that these structures exhibit a behavior characteristic of p-type conductivity. Nanocomposites with copper show a markedly enhanced gas-sensing response to H2S.
