Inverse opal gas sensors : Zn(II)-doped tin dioxide systems for low temperature detection of pollutant gases
journal contribution
posted on 2008-03-14, 00:00 authored by Alessandra SuttiAlessandra Sutti, C Baratto, G Calestani, C Dionigi, M Ferroni, G Faglia, G SberveglieriFocusing here on the effects of zinc doping in a nanocrystalline matrix of tin dioxide, inverse opal prototype sensors are presented and extensively studied as superior candidates for gas sensing applications. Courtesy of factors including controlled porosity, enhanced surface to volume ratio and homogeneous dispersion of species in the crystalline lattice assured by the sol–gel technique, prototype sensors were prepared with high dopant ratios in a range of new compositions. Exploiting their high sensitivities to low-gas concentrations at low working temperatures, and thanks to the presented templated sol–gel approach, the prepared sensors open up new frontiers in compositional control over the sensing oxide materials, consequently widening the possibilities available in on-demand gas sensor synthesis.
