ABSTRACT: Electro-oxidation of methanol in acidic solution was investigated on Au/SnO2 based electrocatalyst obtained by the sol–gel method. Au/SnO2 systems were prepared by one-pot synthesis using a sol–gel method and tin (IV) acetate as a precursor of SnO2 and water solution of HAuCl4 acid as a source of metallic phase. The described method, thanks to its simplicity and mild processing temperature, offers uniform dispersion of metal phase in the bulk of the gel forming as a result of hydrolysis and condensation of tin precursor. It has been found that the obtained system exhibits high electrocatalytic activity.
