Investigations of the effects of iron, manganese, and nickel on the properties of sulfated zirconia catalysts.

Thermogravimetry (TG) was utilized to study catalyst thermal stability and to measure sulfate contents for catalysts with differing compositions. Temperature programmed desorption (TPD) measurements of surface adsorbed species were used to characterize catalyst acidities. Diffuse reflectance Fourier transform infrared spectroscopy (DRIFTS) and variable temperature diffuse reflectance Fourier transform infrared spectroscopy (VT-DRIFTS) were used to characterize adsorbate interactions with catalyst surfaces. Results from TPD studies suggested that metal promoters did not increase the acidity of sulfated zirconia catalysts. Based on TG and VT-DRIFTS studies, a potential structure for sulfated zirconia acid sites was proposed.
