Growth of gold nanoparticle arrays in TiO 2 mesoporous matrixes

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@TiO 2 nanocomposites (5 nm Au particles, 5.5 nm amorphous titania walls) have the electrochemic...
