Abstract

Recently, the suitability of mesoporous materials, mainly those based on SiO2, to be used as filters for solid state gas sensors has been reported. Basic properties of mesoporous based filters are low fluidic resistance as well as high active surface, higher than 100m2/g.
In this work, mesoporous materials have been loaded with different catalytic metals. The presence of nanoclusters of these metallic elements allow to transform molecules flowing through the mesoporous filter.
Morphological, structural and functional characterization of mesoporous loaded materials are presented and analyzed. Data corresponding to their application as active filters of SnO2 based gas sensors measuring combustion gases are also presented.
