Preparation of oxide catalysts and catalyst supports — a review of recent advances

Recent progress in the understanding of the effect of preparation variables on the properties of oxide materials, either to be used as catalysts or catalyst supports, are summarized. The methods include sol-gel technique, use of surfactant to prepare mesoporous and related materials, equilibrium adsorption technique, preparation of hydrotalcite materials, and use of preformed multicomponent complexes. The control of the properties of the oxide material, such as pore size, surface area, and homogeneity by controlling the preparation variables in different methods, and the chemical processes involved in these methods are discussed.
