Sol−gel boehmite was aged under hydrothermal conditions at 200 °C using water as mineralizer agent. Samples were characterized with X-ray powder diffraction, nitrogen adsorption, and transmission electron microscopy. Calcined solids were also studied by infrared spectroscopy of adsorbed pyridine. Their catalytic properties were determined in the 2-propanol decomposition.

Nov 08, 2006 · The specific surface area of ZnAl2O4 obtained after calcination at 500 °C is as high as 253 m2 g-1 and then decreases gradually with calcination temperature. The templating effect of self-generated ZnO is the essential factor directing the formation of the present high-surface-area ZnAl2O4 spinels with interconnected mesopore networks.
