Mesoporous ZrO2-supported iron oxide materials were prepared with nominal loadings of iron oxide of 5, 10, 15 and 20 wt.% using a modified co-precipitation method. The physicochemical properties of the catalysts were characterized by thermogravimetric analysis, differential scanning calorimetry, X-ray diffraction, Raman spectroscopy, high resolution transmission electron microscopy, N2 adsorption, X-ray photoelectron spectroscopy and infrared spectroscopy methods. A delay in ... Read more
