Abstract

Three-dimensionally ordered macroporous titanium dioxide (3DOM TiO ₂) was synthesized through a colloidal crystal template method using self-made poly-(methyl methacrylate) (PMMA) microspheres as a hard template. Nitrogen-doped 3DOM TiO₂ (N-3DOM TiO₂) samples were also prepared by an impregnation method. The samples were characterized by techniques such as SEM, EDX, XRD, TGA, and UV-visible spectroscopy. The photocatalytic activities of these catalysts were tested by degradation of methyl orange (MO) under UV-visible light and visible light respectively. The experimental results show that the 3DOM TiO₂ and N-3DOM TiO₂ exhibited improved optical absorption and subsequently enhanced photodegradation efficiency of MO compared to TiO₂ particles.
