Choice of precursor not affecting the size of anatase TiO2 nanoparticles but affecting morphology under broader viewInternational Nano Letters - Tập 4 - Trang 1-8 - 2014
Manasi Manoj Karkare
In this study, anatase titanium dioxide nanoparticles were successfully prepared by a sol–gel method using two different precursors, titanium isopropoxide and titanium butoxide. Hydrochloric acid or nitric acid was added to adjust the pH of the solution. The sols obtained were dried at 80 °C and calcined at 450 °C for 3 h. The nanostructures were characterised by scanning electron microscopy, FTIR...... hiện toàn bộ
