Available in PDF, EPUB and Kindle. Book excerpt: One of the most pressing challenges of our time is meeting growing global energy demands while limiting human impact on the environment. To meet this challenge, new catalysts are needed to enable carbon neutral energy production processes and low cost synthesis of alternative fuels. In order to design new catalysts for such processes, fundamental understanding is needed on how the structural and chemical properties of nanostructured materials influences their surface chemistry. In this dissertation, I explore how the properties of nanoparticles, such as particle size, shape, composition, and chemical state, can be used to tune their reactivity. For this work, model nanoparticles were synthesized with well-defined structural and chemical properties, and a variety of surface science approaches were used for catalyst characterization. In particular, emphasis was placed on understanding the changes which may occur in the catalyst structure and chemical state during a reaction using advanced in situ techniques and correlating these changes to reactivity. After exploring how nanostructuring the catalyst surface can be used to tune reactivity and how dynamic changes can occur to nanocatalysts in reactive environments, these general principles are applied to a model reaction, the electroreduction of carbon dioxide, which is a promising process for synthesizing valuable products using renewable energy while consuming waste carbon dioxide. I explore the mechanisms behind how catalyst particle size, composition, and oxidation state can be used to improve activity and tune selectivity towards different carbon dioxide reduction products. Such fundamental mechanistic insights are critically needed to design efficient catalysts for this reaction.

Book excerpt: In the course of this PhD thesis, the control and tunability of the reactivity of model nanocatalysts (magnesia supported size-selected metal clusters) were explored. To address dependencies of the catalytic activities on the thickness of MgO films, dimensionalities of adsorbed clusters, and oxygen pre-treatment of catalysts various temperature programmed reaction experiments as well as Fourier transform infrared spectroscopy were carried out in conjunction with first-principles theoretical calculations. Nanocatalytic materials were synthesied using a state-of-the-art cluster vaporisation source. It was demonstrated that reaction pathways involved in the CO combustion over model systems consisting of size-selected metal clusters (Au20, Pd13, and Pd30) varies with the support properties and oxidation state of the cluster catalysts.

Book excerpt: The valorization of lignocellulosic biomass, in the form of forest and agricultural wastes, industrial processing side-streams, and dedicated energy crops, toward chemicals, fuels and added-value products has become a major research area with increasing exploitation potential. The efficient and tailored depolymerization of biomass or its primary structural components (hemicellulose, cellulose, and lignin) to platform chemicals, i.e., sugars, phenolics, furans, ketones, organic acids, etc. is highly dependent on the development of novel or modified chemo- and bio-catalytic processes that take into account the peculiarities and recalcitrance of biomass as feedstock, compared for example to petroleum fractions. The present Research Topic in Frontiers in Chemistry, Section of Green and Sustainable Chemistry, entitled “Nano-(bio)catalysis in lignocellulosic biomass valorization” aims to further contribute to the momentum of research and development in the (bio)catalytic conversion of biomass, by featuring original research papers as well as two review papers, authored and reviewed by experts in the field. The Research Topic addresses various representative reactions and processes in biomass valorization, highlighting the importance of developing novel, efficient and stable nano-(bio)catalysts with tailored properties according to the nature of the reactant/feedstock and the targeted products.

Thanks to the spectacular achievements of colloidal chemistry and the synthesis of nanomaterials over the last two decades, there have also been significant advances in nanoparticle catalysis. Catalysis on different metal nanostructures with well-defined structures and composition has been extensively studied. Metal nanocrystals synthesized with colloidal chemistry exhibit different catalytic performances in contrast to metal nanoparticles prepared with impregnation or deposition precipitation. Additionally, theoretical approaches in predicting catalysis performance and understanding catalytic mechanism on these metal nanocatalysts have made significant progress. Metal Nanoparticles for Catalysis is a comprehensive text on catalysis on Nanoparticles, looking at both their synthesis and applications. Chapter topics include nanoreactor catalysis; Pd nanoparticles in C-C coupling reactions; metal salt-based gold nanocatalysts; theoretical insights into metal nanocatalysts; and nanoparticle mediated clock reaction. This book bridges the gap between nanomaterials synthesis and characterization, and catalysis. As such, this text will be a valuable resource for postgraduate students and researchers in these exciting fields.
