PHOTOCATALYTICALLY PREPARED Au NANOPARTICLES ON TiO_2 NANOTUBES FOR ELECTROCATALYTIC APPLICATION

摘要

Composites containing Au nanoparticles on TiO_2 nanotubes have been produced using photocatalytic deposition. Electrocatalytic activity of the prepared system in oxygen electroreduction reaction was found to depend strongly on the annealing temperature of the TiO_2 support. This effect was explained in the frame of a model supposing the formation of Schottky barrier at the T1O_2-Au interface.
