“…This article must therefore be hereby marked "advertisement" in accordance with 18 U. S. C. §1734 solely to indicate this fact. On the other hand, metal complexes in general, and cobalt complexes in particular, are able to bind CO2 (24)(25)(26)(27)(28)(29)(30)(31)(32) and to act as electrocatalysts for its reduction (33)(34)(35)(36), for instance to CO by the overall reaction 4 (36).…”

Contributed by Jean-Marie P. Lehn, October 8, 1981 ABSTRACT Visible light irradiation of solutions of Ru(2,2'-bipyridine)2+, cobalt(ll) chloride, and carbon dioxide in acetonitrile/water/triethylamine generates simultaneously carbon monoxide and hydrogen. The reaction involves photoinduced reduction of CO2 and H20, triethylamine serving as electron donor in the Ru(2,2'-bipyridine)2+/Co2+ system. The amount of gas (CO

“…126 In aqueous solutions of tetraalkylammonium salts, current-potential curves at a cobalt phthalocyanine (Co-Pc)-coated graphite electrode showed a reduction current peak whose height was proportional to the CO2 concentration and to the square root of the potential sweep rate at a given CO2 concentration. On electrolysis, oxalic acid and glycolic acid were detected, but formic acid was not.…”

“…Such anchoring sites are part of molecular structures of quite different complexity: by controlling the structural parameters of the ligands, it is possible to control the utilization of the metal complexes in the reduction of CO 2 . Mono-, di-and poly-dentate phosphines with moieties of various basicity and acidity strongly influence the properties of the catalyst [19]. N-macrocyclic ligands have been intensively investigated [20][21][22] as well as dipyridine [23].…”

The need to cut CO 2 emission into the atmosphere is pushing scientists and technologists to discover and implement new strategies that may be effective for controlling the CO 2 atmospheric level (and its possible effects on climate change). One option is the capture of CO 2 from power plant flue gases or other industrial processes to avoid it entering the atmosphere. The captured CO 2 can be either disposed in natural fields (geological cavities, spent gas or oil wells, coal beads, aquifers; even oceans have been proposed) or used as a source of carbon in synthetic processes. In this paper, we present the options for CO 2 utilization and make an analysis of possible solutions for the conversion of large volumes of CO 2 by either combining it with H 2 , that must be generated from water, or by directly converting it into fuels by electrolysis in water using solar energy. A CO 2 –H 2 -based economy may address the issue of reducing the environmental burden of energy production, also saving fossil carbon for future generations. The integration of CO 2 capture and utilization with CO 2 capture and storage would result in a more economically and energetically viable practice of CO 2 capture.
