Book Synopsis Heterogeneous Catalysts for Acceptor-less Alcohol Dehydrogenation - Joined Experimental and Theoretical Studies by : Kamila Maria Kazmierczak
Download or read book Heterogeneous Catalysts for Acceptor-less Alcohol Dehydrogenation - Joined Experimental and Theoretical Studies written by Kamila Maria Kazmierczak and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acceptor-less alcohol dehydrogenation is a highly interesting reaction from the green chemistry point of view. In it, the (biomass derived) alcohols are transformed into carbonyl products, which are high value-added chemicals. Moreover, highly-energetic H2 in gaseous form is produced as the only by-product in the reaction. The presence of catalyst facilitates the process. Cobalt heterogeneous supported catalysts and unsupported shaped nanoparticles were investigated in this reaction. To understand their catalytic performance, the experimental and theoretical approaches were joined. Catalytic testing was aiming to assess the activity and selectivity of the catalysts, towards the dehydrogenation of mono- and polyalcohols (diols) possessing primary and secondary hydroxyl groups. Extensive characterization allowed to investigate the intrinsic properties of the materials. In between the reducibility of cobalt supported on materials of different nature was examined. For unsupported nanoparticles the shape, type of exposed metal facets, and also thickness of the ligand layer protecting the nanoparticles were analyzed. Density Functional Theory (DFT) calculations gave the opportunity to understand the catalytic behavior on the molecular level. The catalytic activity and selectivity, and the influence of the co-adsorbed ligands on the catalytic performance of metal, were studied for Co surfaces of different nature. By combining all the results it was possible to identify the factors guiding the catalyst activity.

Book Synopsis Investigating the Surface Chemistry of Hydrogenation Reactions on Supported Metal Catalysts by : Megan Ingalls
Download or read book Investigating the Surface Chemistry of Hydrogenation Reactions on Supported Metal Catalysts written by Megan Ingalls and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic modifiers can impact heterogeneous catalyst selectivity and activity by altering the adsorption preferences and surface reaction paths. Dually coated supported nanoparticle metal catalysts are prepared, with organic modifiers on both metal particles and their oxide support. Thiols are used to modify metals, with the sulfur head group binding to the surface, while phosphonic acids are used to modify the support. Both thiol and phosphonic acid modifiers form self-assembled monolayers (SAM) on the catalyst surface. Cinnamaldehyde hydrogenation was used to probe the performance of the as-prepared catalysts; the selectivity to cinnamyl alcohol could be potentially improved without significant decreases in activity by coating two self-assembled monolayers on the surface of the catalyst. For the dually coated catalyst, the thiol modifier mainly increased selectivity as was expected from previous work, while the phosphonate coating mainly increased the activity. When adding both thiols and phosphonates to the catalysts in different orders, it was found that the selectivity resembled the second SAM that was added to the catalyst. These changes in selectivity from the second SAM added to the surface were less drastic than the selectivity changes from a single SAM on the surface. For the activity of the catalyst, all of the catalysts with phosphonate coating showed increased activity for cinnamyl alcohol production in comparison to the uncoated Pt/Al2O3. The largest increase was seen when phosphonate was added after the thiol, likely from the thiol leaving open the selective active sites that favor cinnamyl alcohol production while the larger amount of phosphonate effected the electronic properties on the surface to increase the rate.A next potential step in this research is to use organic modifiers to tune the performance of single metal atom catalysts on oxide supports. As an initial step towards this goal, a computational model was developed to investigate hydrogenation reactions on a supported single metal atom catalyst. The catalyst modeled was a single Pt atom catalyst on the 101 surface of anatase TiO2. Acetaldehyde and trans-2-butene were used to model the functional groups in cinnamaldehyde that can be selectively hydrogenated. Multiple models were made to observe how the oxidation state of Pt0, Pt2+, and Pt4+ impacts hydrogenation reaction energies. In the Pt0 models, the adsorption of hydrogen to the surface for the reaction was unfavorable. The absence of hydrogen adsorbed to the surface would cause this catalyst to be unable to hydrogenate trans-2-butene or acetaldehyde. Both the Pt2+ and Pt4+ catalysts adsorbed hydrogen very strongly; however, this very low energy state that was created made it unfavorable for the hydrogen to leave the surface to hydrogenate the trans-2-butene and acetaldehyde.

This book was released on 2006-04-11 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fields of hydrodesulfurization (HDS) and hydrodenitrogenation (HDN) continue to attract the attention of researchers in the various disciplines connected to these fascinating problems that represent two of the key outstanding chemical challenges for the petroleum refining industry in view of their very strong environmental and commercial implications. One area that has flourished impressively over the last 15 years is the organometallic chemistry of thiophenes and other related sulfur-containing molecules. This has become a powerful method for modeling numerous surface species and reactions implicated in HDS schemes, and nowadays it represents an attractive complement to the standard procedures of surface chemistry and heterogeneous catalysis, for understanding the complex reaction mechanisms involved in this process. Similar developments have begun to appear in connection with HDN mechanisms, although in a much more modest scale and depth. Some years ago when, encouraged by Prof. B. R. James, this book was planned, several excellent reviews and monographs treating different aspects of HDS were already available including some on the subject of organometallic models. However, it seemed appropriate to try to summarize the most striking features of this chemistry in an updated and systematic way, and inasmuch as possible in connection with the common knowledge and beliefs of the mechanisms of heterogeneous HDS catalysis. Hopefully, this attempt to build some conceptual bridges between these two traditionally separated areas of chemistry has met with some success.
