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.

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。
