A series of silica-supported vanadium oxo complexes has been prepared via water-free grafting VOCl 3 onto the silica surface. The obtained materials have been characterized with Raman, diffuse reflectance FTIR (DRIFT) and UV–vis, 51 V solid-state NMR and X-ray photoelectron spectroscopies, elemental analysis and N 2 physisorption. The samples with a low vanadium loading (1–5%)...
Microwave (MW)-activated oxidative dehydrogenation of ethane is studied using kinetic approach. It consists in the comparison of kinetic dependencies (shape of kinetic equations, “selectivity or yield vs. conversion” curves) and apparent parameters (activation energies) obtained in thermal and MW modes. In the case of VMo and VMoNb oxides a distinct difference between ethane yields was observed at...
