Thermal behavior of copper oxide and titanium dioxide precursors / Nordiana Hashim

Titanium dioxide and copper oxide were prepared via the sol-gel method. Initially, the starting, materials were weighed out grinded in a mortar. Then, the materials were dissolved in the ethanol by using magnetic stirrers. Once the materials were dissolved, gelling agents were added to produce a thick gel of pH between 5 and 6. The gel was slowly dried until all the solvent had evaporated and the temperatures were increased until precursor materials were obtained. The precursor materials were subjected to thermal studies. The thermal behaviors of the samples were characterized using a simultaneous TG-DSC instrument.
