Hydrogen-Etched TiO2−x as Efficient Support of Gold Catalysts for Water–Gas Shift Reaction

Hydrogen-etching technology was used to prepare TiO2−x nanoribbons with abundant stable surface oxygen vacancies. Compared with traditional Au-TiO2, gold supported on hydrogen-etched TiO2−x nanoribbons had been proven to be efficient and stable water–gas shift (WGS) catalysts. The disorder layer and abundant stable surface oxygen vacancies of hydrogen-etched TiO2−x nanoribbons lead to higher mi...

Gold–ceria catalysts for low-temperature water-gas shift reaction

Nanostructured Au–ceria is a promising new catalyst for low-temperature water-gas shift (LTS). Preparation, characterization, and catalytic properties of this material are reported in this paper. Gold–ceria was prepared by deposition–precipitation (DP), coprecipitation (CP), and gelation methods. The gold loading was varied between 1 and 8.3 at.%, while lanthanum used as a dopant in ceria, was ...

Conducting MoS₂ nanosheets as catalysts for hydrogen evolution reaction.

We report chemically exfoliated MoS2 nanosheets with a very high concentration of metallic 1T phase using a solvent free intercalation method. After removing the excess of negative charges from the surface of the nanosheets, highly conducting 1T phase MoS2 nanosheets exhibit excellent catalytic activity toward the evolution of hydrogen with a notably low Tafel slope of 40 mV/dec. By partially o...

Activity and stability of low-content gold–cerium oxide catalysts for the water–gas shift reaction

We report here on the high activity and stability of low-content gold–cerium oxide catalysts for the water–gas shift reaction (WGS). These catalysts are reversible in cyclic reduction–oxidation treatment up to 400 8C, are non-pyrophoric, and are thus potential candidates for application to hydrogen generation for fuel cell power production. Low-content (0.2–0.9 at.%) gold–ceria samples were pre...
