酸处理的多壁碳纳米管（AMWCNT）支持的RU和MNO双金属催化剂为晶醇的液相加氧化准备。制备催化剂的物理化学特性以FTIR，XRD，NH3-TPD，CO2-TPD，TEM和XPS为特征。 MNO物种被加载在碳纳米管的内表面，对RU颗粒分散有帮助。 6％的RU-8％MNO/AMWCNT具有较小的RU粒径，更好的分散体和更多基本位点的最佳催化性能，持续的99.38％的持晶醇转化为85.84％的Cyclohexanol的选择性。讨论了反应条件对液相晶醇合加氧化的影响，并提出了可能的反应路径。
Acid-treated, multi-walled carbon nanotube (AMWCNT) supported Ru and MnO bimetallic catalysts were prepared for liquid phase hydrodeoxygenation of guaiacol. The physicochemical properties of the prepared catalysts were characterized by FTIR, XRD, NH3-TPD, CO2-TPD, TEM, and XPS. MnO species were loaded on the inner surface of carbon nanotubes and were helpful for Ru particle dispersion. The 6%Ru-8%MnO/AMWCNTs with smaller Ru particle size, better dispersion, and more basic sites gave the best catalytic performance of 99.38% conversion of guaiacol and 85.84% selectivity to cyclohexanol. The effects of reaction conditions on liquid phase guaiacol hydrodeoxygenation were discussed and a possible reaction path was proposed.
