These environmental issues are also connected to the inevitable energy supply shortage due to the eventual depletion of fossil fuel sources. As a solution, the technology of recycling CO2 into useful organic materials continues to attract attention. This methodology can be categorized into two main parts: CO2 fixation and CO2 reduction. For both reactions, molecular catalysts based on transition metal coordination complexes and organometallic compounds have been developed and examined. Molecular catalysts can be characterized and iteratively improved at the molecular level through spectroscopic experiments and the isolation of intermediate species, which is particularly advantageous in comparison to heterogeneous catalysts. The fixation of CO2 into organic compounds to form a carbon-carbon bond by using organometallic catalysts is a direct methodology for CO2 utilization and represents the potential reversible storage of electrochemical energy in chemical bonds. The resultant carboxylic acid-containing compounds formed as the initial products can be subsequently converted into other organic materials, even products with new chiral centers. The reduction of CO2 by two electrons (often with a proton donor as a co-substrate) yields carbon monoxide (CO) and formic acid (HCOOH), which can be further converted to useful chemicals. Reduction reactions involving more than two electrons and two protons can produce formaldehyde (HCHO), methanol (CH3OH), and methane (CH4), which are also desirable as chemicals and fuels. For molecular electrocatalysts, more negative potentials than the equilibrium ones for CO2 reduction are generally required; the difficulty is that the equilibrium potentials for CO2 reduction are generally negative of the equilibrium potential for proton reduction to produce H2, representing a competing thermodynamically favored process. A complementary approach to an electrochemical one is to mediate CO2 reduction with photo-induced electron transfer reactions. Photo- and electrocatalytic CO2 reduction can be used to achieve artificial photosynthesis, or the production of commodity chemicals and fuels with renewable energy inputs originating from solar sources. This Research Topic covers the molecular catalysts based on coordination and organometallic compounds for CO2 fixation/reduction. It includes chemical, electrochemical, and photochemical reactions. It also covers systematic studies of reaction mechanisms and the spectroscopic characterization of catalytic intermediates. Molecular catalysts for CO2 fixation/reduction used as co-catalysts with heterogeneous catalytic systems are also included. Non-precious and abundant transition metal catalysts for CO2 fixation/reduction are important for future industrial applications as core components of the next generation of energy technologies.Science: general issuesbicsscartificial photosynthesisCO2 fixationCO2 reductionelectrocatalysisphotocatalysisScience: general issuesIshida Hitoshiedt1325115Machan CharlesedtRobert MarcedtIwasawa NobuharuedtIshida HitoshiothMachan CharlesothRobert MarcothIwasawa NobuharuothBOOK9910557255103321Molecular Catalysts for CO2 Fixation3036595UNINA02608nam 2200685Ia 450 991095877010332120260209221644.00-19-983934-40-19-985300-20-585-33801-90-19-802640-41-280-45255-21-60256-112-5(CKB)111004366527958(EBL)684603(OCoLC)727649098(SSID)ssj0000193074(PQKBManifestationID)11174765(PQKBTitleCode)TC0000193074(PQKBWorkID)10217102(PQKB)11053966(StDuBDS)EDZ0000034592(Au-PeEL)EBL684603(CaPaEBR)ebr10279407(CaONFJC)MIL45255(Au-PeEL)EBL273019(OCoLC)437173392(OCoLC)33666619(FINmELB)ELB165444(MiAaPQ)EBC684603(EXLCZ)9911100436652795819951108d1996 uy 0engur|n|---|||||txtccrThe literary mind /Mark Turner1st ed.New York :Oxford University Press,1996.1 online resource (viii, 187 pages)Description based upon print version of record.0-19-512667-X 0-19-510411-0 Includes bibliographical references and index.Bedtime with Shahrazad -- Human meaning -- Body action -- Figured tales -- Creative blends -- Many spaces -- Single lives -- Language.We usually consider literary thinking to be peripheral and dispensable, an activity for specialists: poets, prophets, lunatics, and babysitters. Certainly we do not think it is the basis of the mind. We think of stories and parables from Aesop's Fables or The Thousand and One Nights, for example, as exotic tales set in strange lands, with spectacular images, talking animals, and fantastic plots--wonderful entertainments, often insightful, but well removed from logic and science, and entirely foreign to the world of everyday thought. But Mark Turner argues that this common wisdom is wrong.
