【 摘 要 】

The work reports the synthesis of nickel nanoparticles supported on thermally reduced graphene oxides (rGO) in the ionic liquid [BMIm][NTf2] through microwave decomposition reaction. Ni@rGO with the polymer poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) as binder was positively tested for its response towards the oxidizing gas nitrogen dioxide (10 ​ppm in air), the reducing gas carbon monoxide (3000 ​ppm in N2) and the volatile organic compound (VOC) acetone (35,000 ​ppm in air). The results from different gases were compared at different temperatures with the best results for NO2 at 200 ​°C. Additionally, it is shown for NO2 gas that the Ni@rGO-PEDOT:PSS polymer composite gives better results than the rGO-PEDOT:PSS polymer composite. After the heat treatment the oxidation state of pure nickel nanoparticles were confirmed by powder diffraction.
