Abstract : Composite materials based on PbO2 containing TiO2 or ZrO2 were prepared from electrolytes containing a suspension of TiO2 or ZrO2 . The contents of foreign oxides in the composite depend on the electrolyte composition and conditions of deposition. When a dispersed phase is incorporated into the composite coating, the dimensions of lead dioxide crystals decrease to submicro-and nano-size. Physico-chemical properties and electrocatalytic activity of composite materials are mainly determined by their chemical composition. The electrocatalytic properties of a composite PbO2 -TiO2 anode vs the oxygen evolution reaction OER and the electrochemical degradation of methyl tert-butyl ether MTBE were investigated.

Keywords : MTBE ZrO2 composite PbO2 TiO2 electrodeposition suspension
