Title
Hollow hybrid titanate/Au@TiO2 hierarchical architecture for highly efficient photocatalytic application
Abstract

•Hollow hybrid titanate/Au@TiO2 hierarchical architecture is prepared.•The architecture possesses hollow sandwich structural configuration.•The photocatalytic performance is enhanced by the hybridization of titanate-Au-TiO2.

Hollow hybrid titanate/Au@TiO2 hierarchical architecture consisting of titanate and anatase titanium dioxide (TiO2) loaded with Au nanoparticles was prepared via a sol-impregnation method combined with a hydrothermal etching process. The titanate/Au@TiO2 architecture possesses unique hollow spherical configuration with Au nanoparticles loaded in the middle of titanate and TiO2 shells and allows to be used as a microreactor for photocatalytic application. The hybrid titanate/Au@TiO2 photocatalyst shows significantly enhanced photocatalytic activity on degradation of methylorange (MO) under UV light irradiation due to the lower electron–hole pairs recombination rate arisen from the synergistic effect of titanate-Au-TiO2 in hybrid hierarchical architecture.
