Preparation and characterization of Al-promoted mesostructured sulfated zirconia catalysts.

Abstract

Two series of Al-promoted sulfated zirconia catalysts with 3% mol Al₂O₃, were prepared. In one case, Al-promoted mesostructured sulfated zirconia (AI-MSZ) catalysts have been synthesized from the template of the Pluronic P123 in queous solution. Zirconium and aluminum hydroxide has been prepared at 100⁰C under hydrothermal condition. In the other case. Al-promoted sulfated zirconia (AI-5Z) has been synthesized by the co-precipitation method. Al-5Z and Al-MSZcatalysts show high thermal stability. AI-MSZ catalysts show higher catalytic activity than Al-5Z.
