Baranova O. Electrocatalysts based on lead dioxide modified by iron group metals

The regularities of lead dioxide deposition in presence of iron group ions on different materials have been studied. Steady-state and cyclic voltammetry chronoamperommetry, impedance spectroscopy, photocou-lommetry, spectrophotommetry, atomic-absorption spectroscopy, high pressure liquid chromatography, scanning electron and transmission microscopy, x-ray defraction, x-ray photoelectron spectroscopy. The iron group ions adsorb on the PbO2 that cause to inhibition of the electrodeposition processes of lead dioxide. The physical-chemical and electrocatalytical properties of obtained catalysts are different from non-doped lead dioxide. In the first time electrodeposition of lead dioxide on iridium dioxide interlayer on titanium, and nanolayer of iridium oxide on boron doped diamond have been investigated. Use Field: waste water treat-ment modules, inorganic compounds synthesis.
