Tổng hợp và đặc trưng của xúc tác SO42-/Al2O3-ZrO2 cấu trúc mao quản trung bình

Abstract

Two series of Al-promoted sulfated zirconia catalysts with 3% mol Al₂O₃ were prepared. In one case, Al-promoted mesostructured sulfated zirconia (Al-MSZ) catalysts have been synthesized from the template of the Pluronic P123 in queous solution. Zirconium and aluminum hydroxide has been prepared at 100^oC under hydrothermal condition. In the other case, Al-promoted sulfated zirconia (Al-SZ) has been synthesized by the co-precipitation method. Al-SZ and Al-MSZ catalysts show high thermal stability. Al-MSZ catalysts show higher catalytic activity than Al-SZ.
