Synthesis and characterization of inorganic materials of great technological application using sol-gel method. Materials such as transition metal oxides and lithiated metal oxides in Li-battery application, that are usually prepared at high temperature, can be prepared at room temperature using sol-gel technique. Metal phosphates that have properties that range from catalysts through nuclear waste disposal to synthetic bone application that are usually prepared using hydrothermal techniques requiring special pressure and temperature, can be prepared using sol-gel technique under ambient conditions.
New carbon/metal oxides, with improved combustion properties in which the ignition temperature and the carbon monoxide evolution are greatly reduced, are another area of research we are pursuing. We have turned our attention recently to the sol-gel preparation of flame retardant materials and smoke reducing agents. All the prepared materials are fuly characterized using several characterization techniques (X-ray power diffraction, TGA/DSC, FTIR, UV-Vis, 400 MHz NMR, etc.) are available in our chemistry department.
