Title
Pt-doped semiconductive oxides loaded on mesoporous SBA-15 for gas sensing
Author
Abstract
SBA-15-based solids combining semiconductive oxides (Sn and In) and noble metal (Pt) were prepared by an incipient wet impregnation method in order to obtain materials for gas sensing. The materials were characterized by XRD, BET adsorption, SEM, and TEM. The BET analysis allowed obtaining details about the specific surface areas, pore size, and modifications due to the indium and/or tin oxides followed by the Pt deposition. XRD data revealed that In2O3 did not enter the mesopores of SBA-15, preventing also the entrance of the Pt nanoparticles in the mesopores. On the other hand, SnO2 nanoparticles further doped with Pt could enter the mesoporous network, affording a SBA-15 material loaded with SnO2 and very small Pt nanoparticles with high dispersion. Tablets obtained by pressing the modified SBA-15 were tested as sensitive materials for propene and hydrogen detection.
