摘要: Six metal oxide samples were prepared by calcination of the corresponding precursors at 500°C for 5 h in air and characterized IR XRD analyses. Their surface areas calculated means BET method. The acidities basicities these oxides estimated thermogravimetrically method adsorption pyridine formic acid as probe molecules. pyrolyses pure ammonium perchlorate (AP) AP mixed with (10% w/w) studied, a dynamic atmosphere N2, thermogravimetric analysis (TG) derivative analysis. A correlation was found between catalytic activities during pyrolysis AP, their acidic-basic characters. activation energies non-catalyzed catalyzed from TG results via Coats-Redfern equation.
