Design Aspects of Doped CeO for Low-Temperature Catalytic CO Oxidation: Transient Kinetics and DFT Approach.

CO elimination through oxidation over highly active and cost-effective catalysts is a way forward for many processes of industrial and environmental importance. In this study, doped CeO with transition metals (TM = Cu, Co, Mn, Fe, Ni, Zr, and Zn) at a level of 20 at. % was tested for CO oxidation.

Molten Salt-Promoted MgO Adsorbents for CO Capture: Transient Kinetic Studies.

Optimization of MgO adsorbents is predominantly focused on the regulation of appropriate adsorption sites for CO associated with Mg-O sites of low coordination. Here, for the first time, we conducted transient kinetic experiments to identify and characterize changes of the CO molecular path in MgO-based CO adsorbents upon the addition of molten salt modifiers. Among the optimized samples, addition of 10 mol % NaNO on the surface of MgO exhibited the highest CO uptake (15.
