摘要
A facile and general route was explored to fabricate porous metal-doped TiO2 nanoaggregates from a titanium glycolate precursor and metal salts, in which the metal salts not only provide the dopant precursor but also favor the formation of a porous structure. The as-prepared Co-TiO2 and Ni-TiO2 nanoaggregates showed higher photocatalytic performance than pure TiO2 nanoparticles, P25, and Zn-TiO2 nanoaggregates, indicating that doping with Co or Ni is an effective approach to improve the photocatalytic efficiency.
