We report the synthesis of polypyrrole (PPy) and polypyrrole/silicon carbide nanocomposites (PPy/SiC) and PPy/SiC/dodecylbenzenesulfonic acid (DBSA) by in situ chemical polymerization and their application as sensors for the detection of highly toxic chlorine gas.

La 1-x Mg x OCl 1-x (x = 0.025, 0.05 and 0.1) and La 0.9 Ca 0.1 OCl 0.9 samples were prepared by a solid state reaction method. The best preparation conditions were determined by means of the differential thermal analysis and thermogravimetry (DTA&TG). The samples were studied by X-ray diffraction (XRD) analysis. Electrical conductivity of La 0.9 Mg 0.1 OCl 0.1 was measured using electrical impedance spectroscopy (EIS). The prototype chlorine gas sensor was constructed from La 0.9 Mg 0.1 OCl 0.1 solid electrolyte. The source voltage (SV) of the constructed device was measured as a function of temperature (500–800°C), Cl 2 gradient partial pressure and time. Similar measurements of SV was carried out in atmosphere of synthetic air in argon.
