GREENHOUSE GASES AND EMISSIONS CONTROL BY NEW CATALYSTS FREE OF PRECIOUS METALS
Studies in Surface Science and Catalysis. 2000.
Abstract:The usage of carbon dioxide as a chemical raw material is very important for the elimination of man-caused damage to the atmosphere. A systematic study of the catalytic properties of super-dispersed powders of iron group metals made at the Peoples’ Friendship University of Russia shows its activity in dry methane reforming and in the hydrogenation of carbon oxides with the C2-C3 olefins formation. The method for obtaining and distributing metal powders effect on the catalytic activity and selectivity, as well as the nature of refractory oxides powders used to fabricate matrices with metal powders, is observed in the article. The correct choice of matrix material allows to minimize the formation of the cooking solution during methane dry reforming.

"HYDROGENATION" Edited by Iyad Karame
InTech 2012 1 - 369
Abstract: The possibility of obtaining olefins from a mixture of carbon oxides with hydrogen at atmospheric pressure, as well as determining the impact of the composition and characteristics of catalysts containing transition metal nanoparticles (Fe, Co, Ni, and Mn) on their activity and olefin selectivity is studied in this article. It is shown that active carbon formed as a result of dissociative adsorption of carbon oxides on the catalyst surface, is involved in the synthesis of hydrocarbons. The differences in the catalytic activity and selectivity of bimetallic samples are probably due to the different spillover rate of weakly bounded hydrogen (HI), as well as the rate of CHx radicals jumper- effect from one center to the others, where further hydrogenation undergoes. An increase of the catalyst dispersion can lead to a redistribution of the HI: HII ratio to weakly bonded hydrogen, which causes an olefin selectivity increase.

INTERACTION BETWEEN CARBON OXIDES, HYDROGEN AND FE2O3 AND AN + 1FENO3n + 1 (A = Gd, Sr, n = 1, 2, ...,)
Russian Journal of Physical Chemistry A, V. 90, №6. 2016. P.1137-1 1142
Abstract: The interaction of hydrogen and oxygen with the surface of FO (III) and complex oxides An+1FenO3n+1 (A=Gd, Sr, n+1,2…. – the number of perovskite layers)was studied by the method of thermos programmable desorption. It was shown that in the case of carbon oxides molecular (forming carbonate-carboxylate complexes), and dissociative absorption occur. The ratio of the adsorption forms of the both oxides is determined by the structure of ferrites, the number of perovskite layers, by the valence state of iron and its coordination saturation. The presence of weakly and firmly bounded hydrogen was established and it was assumed that hydrogen dissolves in the perovskite volume.

Catalytic Hydrogenation of Carbon Monoxide over Nanostructured Perovskite-Like Gandolinium and Strontium Ferrites
Russian Journal of Physical Chemistry A, Vol. 90, No. 5 Pleiades Publishing, Ltd. 2016 p. 926 - 931
Abstract: The catalytic properties in the hydrogenation of carbon monoxide of perovskite-like ferrites (An + 1BnO3n + 1, where n = 1,2,3, ..., ∞, A = Gd, Sr, B = Fe) synthesized by ceramic and sol-gel technologies were studied . A relationship between catalytic activity, olefin selectivity and synthesis methods for complex oxides, the number of perovskite layers, the size of crystallites, the composition and the valence state of iron was established.
