A series of highly active Pt–TiO2 catalysts have been prepared by impregnation methods via different reduction processes and used for catalytic decomposition of benzene. The oxidized and reduced Pt–TiO2 catalysts exhibit apparent differences in physical/chemical features (e.g. particle size, chemical state, and electronic property of Pt nanoparticles, and surface oxygen) and catalytic activities for...
Hydrophobic silica (SiO 2 ) nanoparticles are synthesized directly from the combustion of hexamethyldisiloxane (HMDSO) in a co-flow diffusion flame burner, employing diluted Ar flow in a branch to further control the flow rate of the precursors. In this study, it is found that the diluted Ar flow could change the surface wetting properties of the silica products synthesized by flame approach...
