Abstract

Novel TiO₂ mesocrystalline microrods with unique hexagonal structure were prepared via a facial thermal method. Their photocatalytic performance under UV irradiation was much higher than that of the Degussa P25 benchmark, one of the best commercial polycrystalline TiO₂ photocatalyst. The hexagonal microrods were formed through self-directed self-assembly within intermediate scaffolds.
