摘要
TiO nanotubes promoted with Pt metal were prepared and tested to be the photocatalytic dehydrogenation catalyst in neat ethanol for producing H gas (C H OH → C CHO + H ). It was found that the ability to produce H , the liquid phase product distribution and the catalyst stability of these promoted nano catalysts all depended on the Pt loading and catalyst preparation procedure. These Pt/TiO catalysts with TiO nanotubes washed with diluted H SO solution produced 1, 2-diethoxy ethane (acetal) as the major liquid phase product, while over those washed with diluted HCl solution or H O, acetaldehyde was the major liquid phase product.
