A new method of one-pot synthesis of efficient Au/SnO <inf>2</inf> electrocatalysts for fuel cells
Abstract
<p>Electro-oxidation of methanol in acidic solution was investigated on Au/SnO<sub>2</sub>based electrocatalyst obtained by the sol–gel method. Au/SnO<sub>2</sub>systems were prepared by one-pot synthesis using a sol–gel method and tin (IV) acetate as a precursor of SnO<sub>2</sub>and water solution of HAuCl<sub>4</sub>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.</p>
