Genesis of a highly active cerium oxide-supported gold catalyst for CO oxidation.

X-Ray absorption spectra show that a CeO(2)-supported CO oxidation catalyst prepared from Au(III)(CH(3))(2)(C(5)H(7)O(2)) initially incorporated Au(III) complexes that were catalytically active at 353 K; during operation in a flow reactor, the gold aggregated into clusters and the catalytic activity increased.

Gold Functionalized Supported Ionic Liquids Catalyst for CO Oxidation

The present study tries to give an insight to the combination of the homogeneous and heterogeneous catalytic properties in a new class of materials. Well dispersed gold nanoparticles on an ionic liquid layer supported on a mineral carrier have been prepared. This work is concentrated on the characterizations and understanding of the interactions between all the components of the catalytic syste...

Graphene-supported hemin as a highly active biomimetic oxidation catalyst.

Well supported: stable hemin-graphene conjugates formed by immobilization of monomeric hemin on graphene, showed excellent catalytic activity, more than 10 times better than that of the recently developed hemin-hydrogel system and 100 times better than that of unsupported hemin. The catalysts also showed excellent binding affinities and catalytic efficiencies approaching that of natural enzymes.

Preparation of a Novel Super Active Fischer-Tropsch Cobalt Catalyst Supported on Carbon Nanotubes

The potential of carbon nanotubes (CNT) supported cobalt catalysts for Fischer-Tropsch (FT) reaction is shown. Using the wet impregnation method cobalt on carbon nanotubes catalysts were prepared with cobalt loading varying from 15 to 45 wt. %. The catalysts are characterized by different methods including: BET physisorption, X-ray diffraction, hydrogen chemisorption, and temperature-progra...

Optimization of Preparation Factors for Cerium Oxide Synthesis as a Support for CO PrOx Catalyst

Nanocrystalline ceria has been considered as support for carbon monoxide preferentially oxidation. In this study ceria was prepared by precipitation method and the effects of preparation conditions, such as pH of solution (8-10), aging time (1-12 hr), drying temperature (80-120 °C), calcination time (2-6 hr) and temperature (400-600 °C) were investigated on ceria synthesized powders properties....
