Abstract

The effects of the preparation method on structures and dispersion of FeO_x/SiO₂ catalysts have been investigated by DR-UV-Vis, FTIR and TPR measurements. The efficiency of the preparation route based on "adsorption-precipitation" of Fe²⁺ (ADS/PRC), in enhancing the oxide dispersion is ascertained. The performance of ADS/PRC catalysts in the partial oxidation of CH₄ to HCHO (MPO) is compared with that of conventional systems obtained by "incipient wetness" of silica with aqueous solutions of Fe^III (INC/WET). The ADS/PRC method, enabling a higher dispersion of the active phase, provides very effective MPO catalysts.
