Selective Ethanol Synthesis from Carbon Dioxide ROLES OF RHODIUM CATALYTIC SITES
Work on the synthesis of ethanol from carbon dioxide over a rhodiumselenium catalyst i s reported, and related reactions and characterisation studies are briefly reviewed. I n order to inhibit the formation of methane (complete reduction of carbon dioxide) and simultaneously activate carbon-carbon bond formation by the reaction of CH, with carbonyl derivatives, it is necessary to control the ac...
متن کاملAqueous rhodium(III) hydrides and mononuclear rhodium(II) complexes.
In aqueous solutions, as in organic solvents, rhodium hydrides display the chemistry of one of the three limiting forms, i.e. {Rh(I)+ H+}, {Rh(II)+ H.}, and {Rh(III)+ H-}. A number of intermediates and oxidation states have been generated and explored in kinetic and mechanistic studies. Monomeric macrocyclic rhodium(II) complexes, such as L(H2O)Rh2+ (L = L1 = [14]aneN4, or L2 = meso-Me6[14]aneN...
متن کاملMesoporous metallic rhodium nanoparticles
Mesoporous noble metals are an emerging class of cutting-edge nanostructured catalysts due to their abundant exposed active sites and highly accessible surfaces. Although various noble metal (e.g. Pt, Pd and Au) structures have been synthesized by hard- and soft-templating methods, mesoporous rhodium (Rh) nanoparticles have never been generated via chemical reduction, in part due to the relativ...
متن کاملNuclear Isomerism in Rhodium
Prompt publication of brief reports of important discoveries in physics may be secured by addressing them to this department. Closing dates for this department are, for the first issue of the month, the eighteenth of tke preceding month, for the second issue, the third of tke month. Because of the late closing dates for the section no proof can be shorn to authors. The Board of Editors does not...
متن کاملTerminal imido rhodium complexes.
Compounds of the late transition metals with M=X multiple bonds (X=CR2, NR, O) represent a synthetic challenge, partly overcome by preparative chemists, but with noticeable gaps in the second- and third-row elements. For example, there are no isolated examples of terminal imido rhodium complexes known to date. Described herein is the isolation, characterization, and some preliminary reactivity ...
