Resumen

C02 emissions are one of the main causes of the greenhouse effect. Reactions between C02 and H2, such as methanol synthesis and methanation, could play an important role in reducing these emissions. The low methanol yield, both selectivity and conversion, is the main problem in the methanol synthesis. Methanation could be considered as another alternative process, because recent research showed that the yield in methanation'process is high, the conversion of C02 to C~ was nearly 100%. By using a combination of the Zero Emission Petrol Vehicle (ZEPV) concept, catalytic hydrogenation of CO2 and

Resumen

CO hydrogenation and CO oxidation are two important processes addressing the energy and environmental issues of great interest. Both processes are carried out using metallic catalysts. The objective of this dissertation is to study the catalytic processes that govern these two reactions from a molecular perspective using quantum mechanical calculations. Density Functional Theory (DFT) has proven to be a valuable tool to study adsorption, dissociation, chain growth, reaction pathways etc., on well-defined surfaces. DFT was used to study the CO reduction reactions on promoted cobalt catalyst su

Resumen

During this PhD thesis, cobalt (Co) catalysts have been prepared, characterized and studied in the carbon monoxide hydrogenation (CO+H2) reaction (also known as “Fischer-Tropsch” (FT) reaction). In industry, the FT synthesis aims at producing long chain hydrocarbons such as gasoline or diesel fuels. The interest is that the reactants (CO and H2) are obtained from other carbonaceous sources than crude oil: natural gas, coal, biomass or even petroleum residues. As it is well known that the worldwide crude oil reserves will be depleted in a few decades, the FT reaction represents an attractive al

It was known highly dispersed Co (HDC) catalysts for Fischer-Tropsch applications could be synthesised from either Co metal or CoCO3 precursors. Both synthesis routes were known to precipitate Co oxide nanoparticles from solution onto a support via Co(III) ammine complexes. The synthesis pathway was not known. Using solid state NMR and single crystal X-ray diffraction (XRD) a suite of Co(III) complexes have been characterised. The HDC catalyst synthesis from Co metal produced the Co(III) complex which was identified as [(Co(NH3)3)2(μ-OH)2(μ-CO3)](CO3)∙5H2O via single crystal XRD. The 59 Co sol

Resumen

<p> The catalytic hydrogenations of CO and CO2 to more useful chemicals is not only beneficial in producing more valuable products and reducing dependence on fossil fuels, but present a scientific challenge in how to control the selectivity of these reactions. Using colloidal chemistry techniques, a high level of control over the synthesis of nanomaterials can be achieved, and by exploiting this fact a simple model system can be realized to understand the reaction of CO and CO2 on a molecular level. Specifically, this dissertation focuses on understanding cobalt materials for the conversion of

As an important chemical raw material, alcohols can be used as fuels, solvents and chemical feedstocks to produce a variety of downstream products. With limited fossil fuel resources, alcohol synthesis from syngas reactions can be a potential alternative to the traditional petroleum based alcohol synthesis. Among many catalysts active for syngas to alcohol processes, alkali promoted Mo2C has shown promising performance. More interestingly, the alkali promoter was found to play an important role in shifting the reaction selectivity from hydrocarbons to alcohols. However, limited understanding o

The main objective of this thesis is to develop better catalysts for the hydrogenation of 5- hydroxymethylfurfural, HMF into high quality liquid fuel 2, 5- dimethylfuran (DMF) or partly hydrogenating compounds. This could be achieved by exploiting the support effect and using CNTs to improve activity and developing mono- and bimetallic systems utilising less expensive metals like Nickel, Cobalt or Iron compared to noble metals like ruthenium and rhodium. Succeeding at this could be an economic incentive for the scale-up production of DMF. In addition, we envisaged the opportunity to be able to

博士<br>臺灣大學<br>化學研究所<br>95<br>The heterogeneously catalytic CO Oxidation with Au-Ag alloy deposited on inert and acidic mesoporous aliminosilicate MCM-41 support, prepared by either one-pot or two-step procedure, has been investigated in terms of the experimental kinetics, in-situ DRIFTS, O2 pulse adsorption, O2-TPD and theoretical reaction modeling. For one-pot/3:1 Au-Ag/MCM-41 alloy catalyst, the unexpectedly high catalytic activity at 80oC may be associated with the non-dissociative and non-competitive adsorption Langmuir-Hinshelwood model between CO and O2 species in intimate proximity on t

A Dissertation submitted to the Faculty of Science, University of the Witwatersrand, in partial fulfilment of the requirements for the degree of Master of Science, 2017<br>N-(aryl) salicylaldimine ligands were prepared by the condensation of salicylaldehyde and aniline, 2,6 – dimethylaniline, 2,6 – diisopropylaniline and N,N-diethyl-p-phenylenediamine to give the desired ligands in good yields (70 - 93 % yield). The synthesised ligands were characterised by NMR spectroscopy, FTIR spectroscopy, ESI mass spectrometry and elemental analysis. The purity of these ligands was determined by de

Resumen

碩士<br>國立中央大學<br>材料科學與工程研究所<br>97<br>Hydrogen is viewed as one kind of promising clean fuel of the future. The refueling method, the hydrogen storage, and the handling facilities are critical factors in the development of a hydrogen technology for transportation. An effective hydrogen storage technology is required to make this source of energy economically viable. Li3N is a potential hydrogen storage material owing to its high theoretical H2 capacity (10.4 wt%). In this study, the Pd, Pd-Ni and Pd-Co alloy catalysts were used to modify Li3N to enhance its hydrogenation kinetics. The hydrogenat

Resumen

Pincer complexes moieties have attracted much attention in the past years. They have been proved that they are highly active catalysts in many different known transition metal-catalyzed organic reaction and some unpredictable organic transformation. In this thesis, we will use PN3P Cobalt pincer complex in two different applications. The first application is the unpresented Cobalt-catalyzed hydrogenation of nitriles to secondary imines. The selective hydrogenation of nitriles into secondary imines is a very challenging task and the catalysts play a very important role in the reaction
