Multicomponent Au/Cu-ZnO-Al2O3 catalysts: Robust materials for clean hydrogen production

Viability of Au/CeO2-ZnO/Al2O3 catalysts for pure hydrogen production via WGS

The production of H2 pure enough to use it in fuel cells requires the development of very efficient catalysts for the WGS reaction. In this study a series of gold catalysts supported on ZnO-promoted CeO2Al2O3 is presented as interesting systems for the purification of H2 streams via WGS. The addition of ZnO remarkably promotes the activity of a Au/CeO2/Al2O3 catalyst. This increase in activity ...

Hydrogen production from methanol decomposition over Pt/Al2O3 and ceria promoted Pt/Al2O3 catalysts

We present the activities and selectivities of Pt/Al2O3-based catalysts in the production of hydrogen from methanol through catalytic decomposition. For the decomposition reaction, the Pt and Pd catalysts promoted by ceria exhibit similar activity reaching 100% conversion at 315 C. Promoting with ceria had a positive effect on activity and selectivity. Among all catalysts, the 9% Pt– 10% CeO2/A...

CO x Free Hydrogen Production by Catalytic Decomposition of Methane Over Porous Ni/Al2O3 Catalysts

Meso- and Nanostructuring of Industrial Cu/ZnO/(Al2O3) Catalysts

A concept is presented, which helps to rationalize the success of the industrially applied preparation route for Cu/ZnO/(Al2O3) catalysts. Many studies can be found in the open literature, which describe the critical dependency of the final catalyst’s properties on precursor chemistry. In line with previous reports, this concept identifies zincian malachite as the relevant precursor phase and i...

Hydrogen Rich Fuel Gas Production from 2- Propanol Using Pt/Al2O3 and Ni/Al2O3 Catalysts in Supercritical Water

Hydrogen is an important chemical in many industries and it is expected to become one of the major fuels for energy generation in the future. Unfortunately, hydrogen does not exist in its elemental form in nature and therefore has to be produced from hydrocarbons, hydrogen-containing compounds or water. Above its critical point (374.8C and 22.1MPa), water has lower density and viscosity, and a ...
