Selective oxidation of n-buthanol to butyraldehyde over MnCo2O4 spinel oxides

SELECTIVE OXIDATION OF n-BUTANE TO MALEIC ANHYDRIDE UNDER OXYGEN-DEFICIENT COMDiTIONS OVER V-P-O MIXED OXIDES

The selective oxidation of n-butane to maleic anhydride over V-P-O mixed oxides was studied under oxygen deficient conditions. The mixed oxides were prepared with P/V atomic ratios ranging from 0.7 to 1.0. Catalysts with P/V (1.0 did not show any selectivity to maleic anhydride formation, regardless of whether or not (VO)2P207 was present. For catalysts with P/V = 1.0, containing by &e actual s...

Selective oxidation of 5-hydroxymethylfurfural to 2,5- diformylfuran over intercalated vanadium phosphate oxides

Selective Oxidation of Xylenes to Toluic Acids

A mixture of manganese, cobalt and lead para-amino benzoates supported on silica gel is used to catalyze oxidation of xylenes to toluic acids in presence of oxygen or air. Reactions are clean and catalysts can be recovered easily and reused.

Selective CO Oxidation over Au Supported On Mixed Oxides: Effect of Preparation on Activity and Selectivity

Au/CeLaOx mixed oxide catalysts containing 0.5 to 1.0 wt% Au were prepared via coprecipitation with HAuCl4, the appropriate nitrate precursors, and either urea or Na2CO3 as the precipitant. BET surface area measurements for the Au/CeLaOx catalysts varied in the range of 16-107 m/g depending on the precipitant, aging time, and calcination conditions. The catalysts were tested for the selective o...

Understanding complete oxidation of methane on spinel oxides at a molecular level.

It is crucial to develop a catalyst made of earth-abundant elements highly active for a complete oxidation of methane at a relatively low temperature. NiCo2O4 consisting of earth-abundant elements which can completely oxidize methane in the temperature range of 350-550 °C. Being a cost-effective catalyst, NiCo2O4 exhibits activity higher than precious-metal-based catalysts. Here we report that ...
