Abstract

The aim of this manuscript was the optimization of the synthesis of TiO2 nanoparticles (TiO2 NPs) with conditions that could be easily reproducible at the industrial level. Several procedures were tested and those with C12H28O4Ti and CO(NH2)2 as precursors seemed the most promising and, consequently, were improved with different molar ratios, lower temperatures and the addition of NH4Cl as a secondary dopant of nitrogen. The obtained samples were studied with analytical techniques such as X-ray powder diffraction (XRPD) and field emission scanning electron microscopy (FESEM). To complete the study, dye degradation and bacteriological tests were also performed. The results indicate that it is possible to obtain TiO2 NPs at lower temperatures with respect to those used in the literature; the best candidate that could satisfy all the requirements was a sample with a molar ratio of C12H28O4Ti:CO(NH2)2 at 2:1 and obtained at 50 °C.
