Abstract:
An X-ray diffraction study of the structural features of Pt electrodeposited on Au substrates was performed. The influence of the deposition potential, electrochemical ageing and model catalytic reactions on the structural characteristics of deposits has been analysed. It has been shown that under the conditions employed highly defective electrolytic deposits are formed composed of nm-sized particles (10-30 nm). Electrochemical ageing and model
electrochemical reactions lead to the relaxation of the defect structure of electrodeposited Pt, which is expressed in an increase of lattice parameter and particle size and decrease in the values of strains and density of randomly distributed dislocations. The data obtained showed that the deposition potential is a key parameter determining structural characteristics of Pt electrolytic deposits, and allowed to reveal the minimum of intergrowth degree of Pt nanoparticles.
