摘要

An original gas sensor system dedicated to the selective monitoring of nitrogen dioxide in air has been successfully developed. This device combines the great sensitivity and the partial selectivity toward oxidizing gases of a molecular organic semiconductor, copper phthalocyanine, with the O_3 filtering capability of different carbonaceous nanomaterials located upstream the sensitive layer in the gas flux. The carbonaceous materials are used either as-prepared or modified by physical or chemical treatments. The ability to filter nitrogen dioxide and ozone, has been correlated to both the BET specific surface area determined by N_2 adsorption at 77 K and the presence of chemical functional groups at the surface. A sensing structure is finally proposed using a chemical filter containing nanocarbons, impermeable to ozone and inert toward nitrogen dioxide, leading to a selective NO_2 sensor response.
