Book excerpt: Esta tesis doctoral trata sobre la síntesis, y el estudio de la actividad catalítica de partículas de oro de tamaño inferior a 2 nm, nanoclústers de oro. El interés proviene de la actividad catalítica a temperatura ambiente que tiene el oro cuando las dimensiones son inferiores a aproximadamente los 5 nm. En esta tesis se desarrollan dos métodos de síntesis que permiten obtener clústeres de oro estables con un tamaño de partícula bien definido. En un método se sintetizan nanoclústeres de oro de tamaño inferior a 2 nm, los cuales son posteriormente depositados sobre un soporte. En cambio, el otro método consiste en sintetizar los nanoclústeres de oro directamente sobre el soporte seleccionado. Con este ultimo método, se puede modificar el tamaño de los clústeres de oro alterando la cantidad de precursor de oro durante el proceso de síntesis. De esta manera se puede obtener desde una dispersión uniforme de átomos de oro aislados, clústeres de Au de 2 nm o nanopartículas de más de 10 nm en la superficie del material de soporte. Los catalizadores sintetizados han sido caracterizados mediante distintas técnicas físico químicas: HRTEM, SEM, AFM, XPS and XAS. Además también se ha estudiado la actividad catalítica para la oxidación de CO y materiales carbonosos. Finalmente, se ha relacionado el tamaño de partícula con la actividad catalítica del material.

Available in PDF, EPUB and Kindle. Book excerpt: Properties of nanometer-sized gold (Au) particles, especially those that are protected by a monolayer coating of thiolate ligands, called 'Monolayer Protected Clusters' (MPCs), are of rigorous multidisciplinary interest for their potential applications in catalysis and electronics due to their variation with size. In larger core diameter sizes ( >1.5nm) AuMPCs show metallic behavior as observed from electrochemical measurements. On the other hand, sub-nanometer ([approximate]1.1nm) AuMPCs exhibit molecule-like electronic behavior which is typical of Au38 nanoparticles. The various alkane chain thiols(C4S-C12S) capped Au38MPCs have been examined with independent analytical tools, producing a remarkably consistent picture of these materials. The chemical structure and / or surrounding environment contribute to the electron transfer phenomenon. For rationalizing electron transfer phenomenon it is important to understand the 2D arrangements of AuMPC in the solid state. MPC-based Langmuir monolayers offer particular virtues for the investigation of the correlation between interparticle distance and electron transfer dynamics. To extend charge transfer studies, the charge transfer quenching of photoexcited semiconductor (TiO2) by hexanethiolate AuMPCs with core diameters of 1.1-4.9 nm were employed. The quenching efficiency of AuMPCs was compared using Stern-Volmer plots. The size dependence of the AuMPC plays a vital role on the quenching efficiency. KQ was found to linearly correlate with the MPC capacitance. This suggests that the quenching process is dominantly controlled by the capacitance of the electron acceptor (AuMPC). In the research presented here, characterization of AuMPCs and charge transfer between semiconductor and AuMPCs have been studied through electrochemistry, spectroscopic analysis, and other techniques. The correlation between electron transfer dynamic and interparticle distances in the AuMPCs monolayer has been estimated using Langmuir trough by horizontal touch voltammetry (HTV) measurements.

Book excerpt: Gold, considered catalytically inactive for a long time, is now a fascinating partner of modern chemistry, as scientists such as Bond, Teles, Haruta, Hutchings, Ito and Hayashi opened new perspectives for the whole synthetic chemist community. Recently gold has attracted significant attention due to its advantageous characteristics as a catalytic material and since it allows easy functionalization with biologically active molecules. In this context, when gold is prepared as very small particles, it turns out to be a highly active catalyst. However, such a phenomenon completely disappears when the gold particle size grows into the micrometer range. Therefore, the preparation for obtaining an active gold catalyst is so important. The primary objective of this book is to provide a comprehensive overview of gold metal nanoparticles and their application as promising catalysts.

Available in PDF, EPUB and Kindle. Book excerpt: Gold has traditionally been regarded as inactive as a catalytic metal. However, the advent of nanoparticulate gold on high surface area oxide supports has demonstrated its high catalytic activity in many chemical reactions. Gold is active as a heterogeneous catalyst in both gas and liquid phases, and complexes catalyse reactions homogeneously in solution. Many of the reactions being studied will lead to new application areas for catalysis by gold in pollution control, chemical processing, sensors and fuel cell technology. This book describes the properties of gold, the methods for preparing gold catalysts and ways to characterise and use them effectively in reactions. The reaction mechanisms and reasons for the high activities are discussed and the applications for gold catalysis considered./a
