Ag Catalysts Supported on CeO, MnO and CeMnO Mixed Oxides for Selective Catalytic Reduction of NO by CH.

In the present study CeO, MnO and CeMnO mixed oxide (with molar ratio Ce/Mn = 1) were prepared by sol-gel method using citric acid as a chelating agent and calcined at 500 °C. The silver catalysts (1 wt.% Ag) over the obtained supports were synthesized by the incipient wetness impregnation method with [Ag(NH)]NO aqueous solution.

Modifier Effect in Silica-Supported FePO and Fe-Mo-O Catalysts for Propylene Glycol Oxidation.

Currently, catalytic processing of biorenewable raw materials into valuable products attracts more and more attention. In the present work, silica-supported FePO and Fe-Mo-O catalysts are prepared, their phase composition, and catalytic properties are studied in the process of selective oxidation of propylene glycol into valuable mono- and bicarbonyl compounds, namely, hydroxyacetone and methylglyoxal. A comparative analysis of the main routes of propylene glycol adsorption with its subsequent oxidative conversion into carbonyl products is carried out.
