Abstract
The development of a pore structure through chemical activation allowed the efficient adsorption of NO because of the enlarged specific surface area and pore volume, resulting in a highly sensitive gas sensor. The application of heat treatments and the addition of MWCNTs enhanced the electrical conductivity, effectively reducing the response time of the sensor. In summary, the ability to sense NO significantly improved because of the combined effects of improved porosity and electrical conductivity.
