title: Three-dimensional ordered assembly of thin-shell Au/TiO2 hollow nanospheres for enhanced visible-light-driven photocatalysis.
abstract: An Au/TiO(2) nanostructure was constructed to obtain a highly efficient visible-light-driven photocatalyst. The design was based on a three-dimensional ordered assembly of thin-shell Au/TiO(2) hollow nanospheres (Au/TiO(2)-3 DHNSs). The designed photocatalysts exhibit not only a very high surface area but also photonic behavior and multiple light scattering, which significantly enhances visible-light absorption. Thus Au/TiO(2)-3 DHNSs exhibit a visible-light-driven photocatalytic activity that is several times higher than conventional Au/TiO(2) nanopowders.
