Mesoporous anatase TiO2 nanocups with plasmonic metal decoration for highly active visible-light photocatalysis

This communication describes a method for facile synthesis of mesoporous anatase TiO2 nanocup crystals. The novel cuplike morphology of TiO2 decorated with gold (Au-TiO2) yields remarkably high photocatalytic activity for degradation of methylene blue under visible light irradiation.
