Resumen:
An interconnected Au nanoparticle arrangement is obtained by electrodeposition from Au(III) soluble complexes within the pore system of block-copolymer templated mesoporous titania films. The resulting Au-ñ-TiO2 nanocomposites (5 nm Au particles, 5.5 nm amorphous titania walls) has the electrochemical behavior of a gold electrode of high surface area. The attenuation of Au surface plasmon due to OH electroadsorption and the existence of mixed localized states in these Au-ñ-TiO2 nanocomposites are observed by in-situ spectroelectrochemistry.
