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 ...
متن کاملWater-gas Shift Reaction over Ceria-promoted Pt catalysts
Introduction The fuel processor in which hydrocarbon fuels can be converted into hydrogen has recently attracted much attention as a result of the advancement in the fuel cell technology. In a fuel processor, the water-gas shift (WGS) reaction plays a crucial role in the transformation of CO, a well-known poisonous gas to electrode of fuel cell, into hydrogen through reaction with steam. In WGS...
متن کاملBioreactor Scale-up for Water-Gas Shift Reaction
A scale-up study has been performed with three different size reactors to establish the optimum operating conditions for the hydrogen production from synthesis gas by biological water-gas shift reaction using the photosynthetic bacterium Rhodosprilliunt rubrum. Optimum medium composition and operating conditions previously determined in a bench scale 1.25 L continuous stirred tank reactor (CSTR...
متن کاملHydrogen-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...
متن کاملActivity 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...
