Much attention has been paid to titanium dioxide, since it is a promising material in the fields of energy, environmental compliance, medicine, and so on. We developed a simplest possible one-step and one-pot rapid method for synthesis of spherical mesoporous titanium dioxide nanoparticles by treatment of titanium salt and carboxylic acid in supercritical methanol. Hollow mesoporous nanoparticles were easily obtained by changing the carboxylic acid. In situ doping of rare earth metals was confirmed in the presence of the corresponding metal salt during the one-pot reaction. The nanoparticles were successfully applied as a new material for biolistic bombardment.
