| 摘 要： | 利用水热法制备了3种AlOOH催化剂,对其进行了表征,并用于催化甲醇和一氧化碳反应.结果表明,适宜的AlOOH结构有利于催化甲醇和一氧化碳反应生成高选择性(≥97.28%)的乙醛,且AlOOH结构的差异会导致反应产物分布出现明显区别.其中,结晶度高、孔径较大、能提供CO解离吸附中心且表面具有适宜酸碱性的AlOOH催化剂表现出高的乙醛选择性,推测乙醛的生成是通过中间体CH_3与HCO的偶联实现的.

| Abstract: | The AlOOH catalysts prepared by hydrothermal method were characterized and used for the reaction of methanol and carbon monoxide.The results showed that proper AlOOH structure dramatically improved the selectivity of acetaldehyde(97.28%) for the reaction of methanol and carbon monoxide.AlOOH structural distinction led to the differences of product distribution.Higher crystallinity, larger aperture, extensive CO dissociative adsorption centre and suitable acid-base of AlOOH catalysts significantly promoted selectivity of acetaldehyde.The acetaldehyde generated by the coupling of CH3 and HCO. |
