Opis

Illustrating developments in electrochemical nanotechnology, heterogeneous catalysis, surface science and theoretical modelling, this work describes manipulation, characterization, control, and application of nanoparticles for enhanced catalytic activity and selectivity. It offers experimental and synthetic strategies in nanoscale surface science.

Spis treści

Theory of nanoparticle catalysis and electrocatalysis: theory and modelling of catalytic and electrocatalytic reactions - some selected examples; simulations of the reaction kinetics on nm supported catalyst particles; electronic structure and chemisorption properties of supported metal clusters - model calculations. Model systems - from single crystals to nanoparticles: state-of-the-art characterization of single crystal surfaces; single crystal surfaces as model platinum-based fuell cell electrocatalysts; electrochemical nanostructuring of surfaces; adsorption and reaction at supported model catalysts; size-dependent electronic, structural, and catalytic properties of metal clusters supported on ultra-thin oxide films; physical and electrochemical characterization of bimetallic nanoparticle electrodes. Synthetic approaches in nanoparticle catalysis and electrocatalysis: nanomaterials as precursors for electrocatalysts; preparation, characterization, and properties of bimetallic nanoparticles; physicochemical aspects of preparation of carbon supported Nobel metal catalysis. Advanced experimental concepts: NMR investigation of supported metal catalysts; in situ X-ray adsorption spectroscopy investigations of the carbon-supported pt electrocatalysts; STM and infrared spectroscopy in studies of fuel cell model catalysts. Particle size, support, and promotional effects: electrochemical and chemical promotion on metal films and nanoparticles; metal-supported interaction in low temperature fuel cell electrocatalysis; effects of nanoparticle size, structure, and metal-support interactions; promotion, electrochemical promotion and metal-support interactions; support effects on catalytic performance of nanoparticles; abnormal infrared effects of nanometer scale thins film material of platinum group metals and alloys at electrode/electrolyte interfaces; design of electrocatalysts for fuel cells; effect of particle size and support on some catalytic properties of metallic and
