The effect of carbon nanotubes on the catalytic properties of Rh-Mn-Li/SiO₂ catalysts was investigated for CO hydrogenation. The catalysts were comprehensively characterized by means of X-ray power diffraction, N₂ sorption, transmission electron microscope, H₂–temperature-programmed reduction, CO–temperature-programmed desorption, temperature-programmed surface reaction, and X-ray photoelectron spectroscopy. The results showed that an appropriate amount of carbon nanotubes can be attached to the surface of the SiO₂ sphere and can improve the Rh dispersion. Moderate Rh-Mn interaction can be obtained by doping with the appropriate amount of carbon nanotubes, which promotes the formation of strongly adsorbed CO and facilitates the progress of CO insertion, resulting in the increase in the selectivity of C₂⁺ oxygenate synthesis.

研究了碳纳米管对Rh-Mn-Li / SiO ₂催化剂催化CO加氢性能的影响。通过X射线功率衍射，N ₂吸附，透射电子显微镜，H _2-程序升温还原，CO-程序升温脱附，程序升温表面反应和X射线光电子能谱对催化剂进行了全面表征。结果表明，可以在SiO ₂的表面附着适量的碳纳米管。球形，可以改善Rh的分散性。通过掺入适量的碳纳米管可以获得适度的Rh-Mn相互作用，这促进了强吸附的CO的形成并促进了CO的插入，从而增加了C ₂ ⁺含氧化合物合成的选择性。
