Book Synopsis Novel Photodeposited Catalysts for Carbon Monoxide Oxidation and Preferential Oxidation of Carbon Monoxide in the Presence of Hydrogen (PROX) by : Sze Chi Chan
Download or read book Novel Photodeposited Catalysts for Carbon Monoxide Oxidation and Preferential Oxidation of Carbon Monoxide in the Presence of Hydrogen (PROX) written by Sze Chi Chan and published by ProQuest. This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: It has been shown that gold nanoparticles supported on metal oxides with sizes below 5 nm exhibit unique catalytic properties for CO oxidation, water-gas shift, and epoxidation of propylene. In particular, Au/TiO 2 exhibits CO oxidation activity at temperature as low as 90 K. Recent research reported that silver nanoparticles supported on TiO 2 are similar to Au nanoparticles supported on TiO 2 . Conventional methods for preparing Ag/TiO 2 and Au/TiO 2 supported catalysts include deposition-precipitation, wet impregnation and co-precipitation. Among these methods deposition-precipitation has shown the best results for these reactions due to the narrow size distribution of Ag and Au. The major disadvantage of the deposition-precipitation method is that Au and Ag particle sizes are very sensitive to precursor concentration. Preparation of Au particles less than 5 nm requires a low precursor concentration and low Au loading. In this work, a different approach, photodeposition, was used to prepare Ag and Au nanoparticles supported on TiO 2 . The main shortcoming of photodeposition is that its efficiency is very sensitive to both bulk and surface structural features. However, such problems can be overcome by reducing the size of TiO 2 particles to the nanoscale. Photodeposition of Ag nanoparticles on commercial TiO 2 particles and nanoparticles was performed on microscope grid-supported samples in order to provide direct visualization of the spatial distribution of photoactive sites on sub-micron-scale and nanoscale TiO 2 particle surfaces and to create materials for potential catalytic applications. HRTEM (high-resolution transmission electron microscopy) and HAADF-STEM (high-angle annular dark-field scanning transmission electron microscopy) were used to characterize these materials. The size and spatial distributions of the Ag nanoparticles on the commercial TiO 2 were not uniform; the concentration of Ag was higher on grain boundaries and at the edges of these submicrometer particles. In the case of TiO 2 nanoparticles, the size distribution of the Ag nanoparticles deposited was relatively uniform and independent of irradiation time and photon energy. The amount of Ag deposited on TiO 2 nanoparticles was at least 6 times higher than that on commercial samples for comparable irradiation conditions. Compared to the case of Ag photodeposition, the difference in the amount of Au photodeposited on TiO 2 particles and nanoparticles was even greater, especially at low precursor concentration. Photodeposition on TiO 2 nanoparticles is suggested as a potential method for the preparation of Ag/TiO 2 and Au/TiO 2 catalysts. The high photoreactivity of TiO 2 nanoparticles makes them an ideal material for preparation of supported metal catalysts when highly uniform nanoscale particle size is required. Extending the previous work, the Ag and Au photodeposition on TiO 2 nanoparticles were scaled-up from micro scale to laboratory scale to generate sample powders in sufficient quantity to be utilized in catalytic reactor. Most of the methods published for the preparation of metal-decorated TiO 2 by photodeposition involve suspended particles in a aqueous media. Our approach for the scale-up process was different, and was developed based on the sample preparation for metal photodeposition on microscope grids. A thin film of TiO 2 nanoparticle powders coated on a glass plate was obtained by using a spin-coating technique before metal photodeposition. Several commercial TiO 2 nanoparticles were used in this study, in order to choose appropriate samples for the scale-up experiments. Preliminary studies of the photoreactivity of commercial TiO 2 nanoparticles for Ag photodeposition on a microscope grid were carried out prior to the scale-up process. The effects of Ag photoreduction conditions, in particular the radiation source and the metal precursor solution concentration, on Ag photodeposition were investigated to determine the optimum conditions for the scale-up process. The size and spatial distribution of Ag nanoparticles, as well as the Ag loading on commercial TiO 2 nanoparticles for the scale up process under various conditions were determined using TEM and HAADF-STEM techniques. After the optimal conditions for the scale-up process were established, Ag/TiO 2 and Au/TiO 2 nanoparticles obtained from the scaled-up process were characterized by atomic absorption spectroscopy (AAS), X-ray diffraction (XRD), Xray photoelectron spectroscopy (XPS) and HAADF. In addition, Ag/TiO 2 and Au/TiO 2 nanoparticles were also prepared using traditional deposition-precipitation methods. The catalytic performance of Ag/TiO 2 and Au/TiO 2 nanoparticles prepared using two different methods for CO oxidation and preferential oxidation of CO in the presence of H 2 (PROX) were investigated using a high-throughput reactor. Results obtained from this study showed that the size of Ag particles, Ag loading, as well as preparation method contributed to the difference in activity of Ag/TiO 2 for CO oxidation and PROX. In the case of Au/TiO 2 the difference in activity for CO oxidation and PROX is mainly due to the preparation method and Au loading.

Download or read book Calorimetry and Thermal Methods in Catalysis written by Aline Auroux and published by Springer Science & Business Media. This book was released on 2013-09-18 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is about calorimetry and thermal analysis methods, alone or linked to other techniques, as applied to the characterization of catalysts, supports and adsorbents, and to the study of catalytic reactions in various domains: air and wastewater treatment, clean and renewable energies, refining of hydrocarbons, green chemistry, hydrogen production and storage. The book is intended to fill the gap between the basic thermodynamic and kinetics concepts acquired by students during their academic formation, and the use of experimental techniques such as thermal analysis and calorimetry to answer practical questions. Moreover, it supplies insights into the various thermal and calorimetric methods which can be employed in studies aimed at characterizing the physico-chemical properties of solid adsorbents, supports and catalysts, and the processes related to the adsorption desorption phenomena of the reactants and/or products of catalytic reactions. The book also covers the basic concepts for physico-chemical comprehension of the relevant phenomena. Thermodynamic and kinetic aspects of the catalytic reactions can be fruitfully investigated by means of thermal analysis and calorimetric methods, in order to better understand the sequence of the elemental steps in the catalysed reaction. So the fundamental theory behind the various thermal analysis and calorimetric techniques and methods also are illustrated.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The environmental applications of oxidation catalysis were examined as part of a two-stage strategy for the reduction of nitrogen oxides (NOx) and also for the removal of carbon monoxide from hydrogen streams. Cobalt-based catalysts were examined. Reduction of NOx, Co/TiO2 and Co/ZrO2 were studied for the oxidation of NO to NO2 in excess oxygen. NO oxidation was studied as the first step in a two-step catalytic scheme where NO is oxidized to NO2 and, in turn, NO2 is reduced with CH4 to N2 under lean conditions. Catalysts were prepared by sol-gel and incipient-wetness impregnation techniques. It was found that increasing the calcination temperature had an adverse effect on the activity of the IWI catalysts. Catalyst characterization showed higher activity for NO oxidation on Co/ZrO2 than on Co/TiO2 which was observed to correlate with the formation of the Co3O4 phase. For the preferential oxidation of CO, cobalt on several metal oxide supports were investigated and showed the highest activity on Co/ZrO2. A variety of reaction experiments were performed to examine the effects of reactant concentrations, residence time, and temperature on the CO conversion and O2 selectivity to CO2.
