    Abstract

    The morphology-controlled gold nanoparticles architectures was facile fabricated by electrolyte-induced agglomeration and their photoelectrochemical applications. The multistructures consisting of gold nanoparticles and sulfur-containing porphyrin or ruthenium complexes were alternatively fabricated, by using gold-sulfur self-assembling, to achieve three-dimensional networks of gold nanoparticles and dyes via covalent bonding. A planar gold electrode was prepared by vacuum deposition of titanium followed by gold onto a glass plate at 300°C. An anodic photocurrents were generated from the RuVS-modified electrodes in the 0.4 to 0.4 V region of applied voltage, in the presence of 0.05 mol dm -3 TEOA.
