Preparation, characterization and catalytic activity of WO3 supported on sulfated tin oxide catalysts
Solid acid catalysts of 15 wt.%SO4/SnO2 loaded with 5–45 wt.%WO3 were prepared, calcined at 400–800 °C, and then characterized by TG–DTA, XRD, FT-IR spectra and nitrogen adsorption techniques. The surface acidity was determined by potentiometric titration with n-butylamine in acetonitrile and FT-IR...
