The catalytic activity of Cr/SiO2 (0.43 to 2.8% chromium by weight), prepared by the ion exchange method, for the dehydrogenation (573 K to 673 K)and oxidative dehydrogenation (503 K to 558 K) of alcohols has been investigated. ...

The effect of zinc on the performance of hematite-based catalysts in ethylbenzene dehydrogenation was studied. Zinc acts as a structural promoter stabilizing the active phase of the catalysts.

The interaction of NH3 with different Fe clusters and nanoparticles was evaluated using a periodic density functional theory method. The preferred adsorption sites, adsorption energies of NH3, the transition states and the ...

Co and Mn molybdates were used for this reaction. After use, their structure remained the same. However, only the Co molybdate maintained the surface area and the catalytic properties after 48 h on stream.
