Cristian Vasquez, G. ; Andrea Peche-Herrero, M. ; Maestre Varea, David ; Cremades Rodríguez, Ana Isabel ; Ramirez-Castellanos, Julio ; Gonzalez-Calbet, José M. ; Piqueras de Noriega, Javier | RSC Royal Society of Chemistry | 2013Cr doped TiO_2 rutile nanoparticles have been used as precursor of microrods and microtubes grown by a vapor-solid method. The grown microstructures have nearly square cross-sections of a few microns wide and lengths of up to about 100 microns. [...]texto impreso

Chemistry | 2014Anatase TiO_2 nanoparticles doped with Al or Fe have been synthesized via a modified Pechini method which allows to reach high control in size and composition. Microstructural analysis onfirms the good crystallinity of the doped anatase nanopar[...]
