TiO₂ Nanotubes: Metal‐Cluster‐Decorated TiO₂ Nanotube Arrays: A Composite Heterostructure toward Versatile Photocatalytic and Photoelectrochemical Applications (Small 5/2015)

Glutathione-capped gold clusters and highly ordered nanoporous layer-covered TiO2 nanotube arrays (NP-TNTAs) are employed as nanobuilding blocks for a well-defined Au/NP-TNTA heterostructure via electrostatic self-assembly. On page 554, B. Liu and co-workers show how tailor-made Au clusters are evenly distributed on the interior and exterior surfaces of the framework. Versatile photocatalytic performances are demonstrated, including the oxidation of organic pollutants, reduction of aromatic nitro compounds, and water splitting.
