This book was released on 2011 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: The studies in this thesis have focused on the chemistry of transition metal complexes related to solar energy storage: electrochemical H2 production, HX splitting and CO2 activation mediated by transition metal complexes. Transition metal complexes, for example with macrocyclic ligands, can catalyze electrochemical proton reduction, a half reaction of water splitting to H2/O2 by electricity generated by sunlight. The strategy for designing efficient molecular catalysts were explored by introducing a Hangman scaffold into metallomacrocyles. The study exhibits synthesis and electrochemistry of metallomacrocyles, and an example of Hangman effect for electrochemical H2 production. Thermodynamically demanding HX splitting to H2/X2 by sunlight can be a promising method for solar energy storage. To date, most HX splitting chemistry was studied with metal complexes based on 2"d or 3 rd row transition metals. Hence, the usage of cheaper first row metals is an imperative to discover economically viable catalytic systems. HX chemistry of Ni complexes and photoelimination of H2 from Ni hydride complexes, and photoactivation of Ni-Cl bonds were studied. CO2 can be utilized as a carrier of H2 by the syntheses of liquid fuels from CO2 and H2. The challenge of using CO2 as a precursor for organic molecules is the activation of strong O=CO bonds. The reaction with metal complexes is one of the methods to break or weaken the bonds. The CO2 chemistry of Ni complexes was explored, and generation of a new binding mode of CO2 and activation of CO2 to CO were studied.

Download or read book Reaction Mechanisms in Carbon Dioxide Conversion written by Michele Aresta and published by Springer. This book was released on 2015-11-07 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an analysis of the reaction mechanisms relevant to a number of processes in which CO2 is converted into valuable products. Several different processes are considered that convert CO2 either in specialty chemicals or in bulk products or fuels. For each reaction, the mechanism is discussed and the assessed steps besides the dark sites of the reaction pathway are highlighted. From the insertion of CO2 into E-X bonds to the reduction of CO2 to CO or other C1 molecules or else to C2 or Cn molecules, the reactions are analysed in order to highlight the known and obscure reaction steps. Besides well known reaction mechanisms and energy profiles, several lesser known situations are discussed. Advancing knowledge of the latter would help to develop efficient routes for the conversion of CO2 into valuable products useful either in the chemical or in the energy industry. The content of this book is quite different from other books reporting the use of CO2. On account of its clear presentation, “Reaction Mechanisms in Carbon Dioxide Conversion” targets in particular researchers, teachers and PhD students.

Download or read book Carbon Dioxide Chemistry Capture and Oil Recovery written by Iyad Karamé and published by BoD – Books on Demand. This book was released on 2018-08-16 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fossil fuels still need to meet the growing demand of global economic development, yet they are often considered as one of the main sources of the CO2 release in the atmosphere. CO2, which is the primary greenhouse gas (GHG), is periodically exchanged among the land surface, ocean, and atmosphere where various creatures absorb and produce it daily. However, the balanced processes of producing and consuming the CO2 by nature are unfortunately faced by the anthropogenic release of CO2. Decreasing the emissions of these greenhouse gases is becoming more urgent. Therefore, carbon sequestration and storage (CSS) of CO2, its utilization in oil recovery, as well as its conversion into fuels and chemicals emerge as active options and potential strategies to mitigate CO2 emissions and climate change, energy crises, and challenges in the storage of energy.
