Abstract

The effect of the type of precursor used in the preparation of pure and modified aluminium oxide (Al2O3, as an acidic oxide) and magnesium oxide (MgO, as a basic oxide) on their structural and surface properties were studied and characterized using different physico-chemical techniques. Thermal analyses (including thermogravimetry, differential thermal analysis) and X-ray diffraction analysis were performed to analyze all the oxide catalyst samples under investigation. In addition, measurements of the acidity and basicity of all samples were performed via the temperature programmed desorption of basic or acidic probe molecules (pyridine and formic acid, respectively) using the thermogravimetric analysis technique.
