摘要：
A preparation of three-dimensionally ordered arrays of N-doped mesoporous TiO2 spheres by a dual-templating synthesis approach employing a combination of both polymer inverse opal templating (hard-templating) and surfactant templating (soft-templating) techniques was developed in this work. The N-doped mesoporous TiO2 spheres were composed of nanocrystalline anatase titania and exhibited wells defined mesoporous structure. The ordered arrays of N-doped mesoporous TiO2 spheres showed enhanced visible light photocatalytic activity, which could be attributed to the N doping effect, abundant ordered mesopores and unique opal structure. Such obtained TiO2 sphere arrays may be promising for practical applications in the fields of environmental purification, water photoelectrolysis and dye-sensitized solar cells.
