Synthesis and Gas Sensing Properties of Palladium Doped Titanium Dioxide Nanoparticles

Abstract:

Pd doped TiO₂ nanoparticles were synthesized by sol-gel method with tetrabutyl titanate and palladium chloride as precursor materials. The products were characterized by XRD, SEM, FTIR and ICPOES technologies. The gas sensing properties of the products to 2-chloroethanol vapor were investigated. The results showed that the optimum concentration of Pd in the TiO₂ nanoparticles was 3 mol% when the particle size of the anatase TiO₂ nanoparticles was about 7 nm. Compared with pure TiO₂ nanoparticles, the 3mol% Pd doped TiO₂ nanoparticles exhibited higher gas sensing activities to 2-chloroethanol vapor.
