Abstract
The sensing properties of SnO2-based elements to CO are markedly impro ved by the addition of a Rh catalyst. The sensor obtained by Rh loadin g has a nonhomogeneous structure. Rh modifies the surface properties o f the sensor obtaining a sensitivity to 100 ppm CO as high as 1100, an d a reduced cross sensitivity to NO(x).
