Abstract:
Development of efficient anodes for fuel cells, e.g. DMFC, implies understanding effects of metal particle size and structure on their catalytic properties. The present paper demonstrates a possible approach to design model catalytic materials for studying size effects in electrocatalysis. Two types of materials are considered: (i) monoblock (single cryst.) Pt nanoparticles and (ii) Pt particles with nanocryst. structure (i.e., particles consisting of a no. of nano-sized grains connected to each other via grain boundaries), in order to investigate the effect of grain boundaries on the adsorption and catalytic properties. Carbon-supported nanostructured Pt electrodes were tested in a no. of electrochem. reactions, relevant to low temp. fuel cells, including hydrogen and oxygen electrochemisorption, electrooxidn. of adsorbed CO, and in ethylene glycol oxidn. Remarkable effects of Pt particle size and nanostructure on the reaction overvoltages, adsorption properties, electrocatalytic activities and selectivities in model processes, as well as the tolerance to self-poisoning have been established. A variety of novel results has been obsd. and studied, which may be used to improve the operation of the direct fuel cell anodes (decrease overvoltage, increase tolerance to self-poisoning, etc.) via controlled synthesis of carbon supported Pt nanoparticles with desired size and nanostructure.
