| Abstract | : | Sulfated zirconia (SZ) catalysts were prepared by impregnation from commercial zirconia nanopowder with different concentrations of sulfuric acid (0.2, 0.5, and 0.8 M) and calcination temperatures (600, 700, 800, and 900 OC). SZ catalysts were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Transmission electron microscopy (TEM), Surface area analyzer (SAA), and acidity test by ammonia adsorption. FTIR showed that the modification of zirconia with sulfuric acid enhanced the catalysts acid sites which confirmed by acidity test and it also showed the 0.8 M SZ at 600 OC was the optimal condition with the highest acidity value of 3.81 mmol/g. XRD showed that SZ crystalline structure was in a monoclinic phase and the intensity decreased with increasing concentration and decreasing calcination temperature. |
