Choice of precursor not affecting the size of anatase TiO2 nanoparticles but affecting morphology under broader view
International 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
Effects of multi-walled carbon nanotubes on flame retardation and thermal stabilization performance of phosphorus-containing flame retardants in polypropylene
International Nano Letters - Tập 2 - Trang 1-7 - 2012
Mohammad Shahvazian, Mehdi Ghaffari, Hoda Azimi, Reza Jahanmardi
Effects of multi-walled carbon nanotubes (MWNTs) on flame retardation as well as thermal stabilization efficiency of two phosphorus-containing flame retardant systems i.e., ammonium polyphosphate/pentaerythritol (APP/PER) and red phosphorus (RP) in polypropylene (PP) have been investigated. Limiting oxygen index, thermo-gravimetric analysis, melt flow index, and tensile tests have been performed i...... hiện toàn bộ
Facile synthesis and characterization of TiO2 nanoparticles: X-ray peak profile analysis using Williamson–Hall and Debye–Scherrer methods
International Nano Letters - Tập 11 - Trang 241-261 - 2021
S. Mustapha, J. O. Tijani, M. M. Ndamitso, A. S. Abdulkareem, D. T. Shuaib, A. T. Amigun, H. L. Abubakar
In this study, TiO2 nanoparticles were synthesized by a sol–gel method involving the interaction of the titanium isopropoxide precursor and sodium hydroxide followed by calcination at a temperature of 450 °C. The effects of stirring time and solution pH on the morphology, phase types and crystallite sizes were investigated. The prepared TiO2 nanoparticles were characterized using X-ray diffraction...... hiện toàn bộ
