A facile and general synthesis strategy to doped TiO2 nanoaggregates with a mesoporous structure and comparable property

Abstract

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.
