Microcalorimetric, infrared spectroscopic, and temperature-programmed-desorption studies are combined with quantum-Ž . chemical calculations based on density-functional theory DFT to study the adsorption of acetaldehyde, methyl acetate, ethyl acetate, and methyl trifluoroacetate on amorphous silica.
## Abstract Different ratios of phosphotungestic acid supported on silica gel were prepared by an impregnation method with PWA loadings ranging from 1 to 30% w/w and calcined at 350 and 500 °C for 4 h in a static air atmosphere. The catalysts were characterized by thermogravimety (TG), differential
