Composition of catalytic layers prepared by ion beam assisted deposition of dysprosium and platinum from a pulsed arc discharge plasma onto carbon catalysts carriers
Plasma produced in metal vapors of a low-voltage vacuum arc discharge between two metal electrodes at their periodic contact was used to preparation surface catalytic layers by ion beam assisted deposition (IBAD) of dysprosium and platinum onto special carbon fiber catalysts carriers. Formation of layers in IBAD mode, by means of the deposition of metal and mixing of precipitating layer with the substrate by accelerated (U = 5 kV) ions of the same metal, was carried out. In this process, a neutral fraction of metal vapor and ionized plasma of vacuum pulsed electric arc were used. Investigation of the composition of prepared layers was carried out by EDX, SEM, RBS and WD-XRF methods. Electrocatalysts with the prepared layers are active in the oxidation of methanol and ethanol reactions, which are the basis of the principle of operation of low-temperature fuel cells.
