Series of ZrO2 supported on the different kinds of SiO2 carriers were applied in the reaction of 1, 3-butadiene formation from ethanol and acetaldehyde. ZrO2/Nano-SiO2 performed the best performance with the 1, 3-butadiene selectivity 91.43% and the total conversation 52.39%. Prepared catalysts were characterized by N2 adsorption–desorption, TEM, XRD, temperature-programmed desorption of NH3 and CO2, FTIR spectroscopy of adsorbed pyridine and CO2, Raman XPS. The results show that the weak Lewis acid and basic sites are appropriate for BD formation. Furthermore, more and balance acid-basic sites are rather important for the reaction of ethanol and acetaldehyde conversion to BD.

Zr-Si材料催化乙醇和乙醛转化为1,3-丁二烯

负载在不同种类SiO 2载体上的ZrO 2系列被用于由乙醇和乙醛形成1,3-丁二烯的反应中。ZrO 2 / Nano-SiO 2表现最佳,其1,3-丁二烯选择性为91.43%,总转化率为52.39%。通过N 2吸附-脱附,TEM,XRD,NH 3和CO 2的程序升温脱附,吸附的吡啶和CO 2的FTIR光谱对催化剂进行了表征。,拉曼XPS。结果表明弱的路易斯酸和碱性位点适合于BD的形成。此外,更多且平衡的酸碱位对于乙醇和乙醛转化为BD的反应非常重要。
