Production of catalytic layers for hydrogen power industry requires the solution of a wide range of complicated physical problems connected with production of pore structure that has a high ratio of specific surface and material volume and also guarantee the high adhesion between membrane and catalyst. Methods of ion treatment are very prospect for production of articles with necessary parameters/now in low temperature fuel elements materials of platinum group are widely used as catalysts of chemical processes; these catalysts are deposited on different carbon carriers, the carbon black is the main carrier. Such materials as carbon nano fibres and nano tubes have a good thermal conductivity, high specific surface and mechanical properties relatively to composite electrode materials and substrates. Due to this nano structurized carbon may be successfully used as the carrier of clusters of platinum group metals with high uniform dispersivity and due to its structure may promote the increase of electron conductivity in catalytic layer.
The special properties on carriers are related with different factors such as electron interaction of deposited material and the base, singularities of crystallographic structure of deposited particles and other. For the increase of catalytic activity of catalysts it is necessary that carrier had the nano structural size. In the paper the investigation of the effect of accelerated particles on the change of the base properties in presence of the metal-catalyst is carried out.
The assembly for production of nano carbon materials with increased electric conductivity is developed. The obtained nanostructurized material represents multi walls nano tubes. For deposition of atoms of metal-catalysts Pt and Ru on nanostructirized graphite particles methods of catalysts deposition by beams of charged particles Ar+ and their activation by beams of H+ and He+ were developed.
The angular dependencies of the flux of sputtered platinum atoms under bombardment by argon ions are calculated by the method of binary collisions. Plots of energetic distribution of sputtered particles are analyzed. Conditions (angle of incidence and energy of bombarding particles of inert gas) for production of platinum ion beams with high adhesion power to carbon nano materials are determined.
