| Abstract Scope |
Titanium oxide nanoparticles were synthesized by green chemistry technique, using aloe vera extract, titanium chloride (2 M, TiCl4) in 1000 mL of ultra-pure water, where aloe vera extract was added drop by drop and kept with constant agitation of 400 rpm, having a pH ~ 7 with HCl or NaOH. The synthesis product was recovered by centrifugation (10,000 rpm) and washed repeatedly with absolute ethanol. The nanoparticles were washed again with ultra-pure water and dried at 100 °C for 7 h, at the end of drying, a fine white powder was obtained which was characterized by X-ray diffraction, where it was determined that the anatase phase (TiO2) was obtained, so it has a tetragonal structure, with cell parameters of a = 3.79 Å, c = 9.51 Å. From the synthesis product nanoparticles of sizes ranging from 2 to 30 nanometers have been obtained, this was confirmed by transmission electron microscopy. |
