Metal oxides are important catalysts in the petrochemical industry and fine chemical industry. Recently, mesoporous transition metal oxides as catalysts have received enormous attentions due to their excellent catalytic properties attributed to high surface area and highly ordered crystalline framework. Various methods for the preparation of mesoporous transition metal oxides have been developed. Among them, the nano-replication method has brought forward incredible possibilities in preparing new mesoporous materials. This study focuses on the process to produce butene via dehydration of butanol. There is an imbalance between demand and supply in the butene market due to rising naphtha prices according to rising oil prices. In this study, 2-butanol dehydration is used to demonstrate the potential advantages of the highly ordered crystalline nanoporous tungsten oxide, which was obtained from a mesoporous silica template. BET, XRD, NH3-TPD, and pyridine-IR were used to study the structural properties of the highly ordered mesoporous WO3 catalyst. The highly ordered mesoporous WO3 catalyst prepared from a mesoporous silica template can be an effective catalyst for producing butenes through 2-butanol dehydration.
