The role of Cs and Cl in promoting selectivity in ethene epoxidation over a Ag/α-Al2O3 catalyst was examined by determining their effect, singly and in combination, on the kinetics of adsorption and desorption of oxygen on that catalyst. Cs has been

The partial oxidation of CH3OH to CO2 and H2 over a Cu/ZnO/Al2O3 catalyst has been studied by temperature-programmed oxidation (TPO) using N2O and O2 as the oxidant. Post-reaction analysis of the adsorbate composition of the surface of the catalyst w
