The MCM-41 mesoporous molecular sieve was modified with Ru using in-situ synthesis, ion-exchange and impregnation catalyst preparation methods. The physico-chemical properties of the Ru–MCM-41 synthesized catalysts were studied using characterisation techniques such as X-ray powder diffraction, scanning electron microscopy, energy dispersive X-ray micro-analysis, X-ray fluorescence, XPS and nitrogen adsorption. The hydrogenation of cinnamaldehyde was used as a test reaction to evaluate the catalytic properties of the Ru–MCM-41 catalysts.

Ru–MCM-41介孔分子筛催化剂的理化和催化性能：Ru改性方法的影响

利用原位合成，离子交换和浸渍催化剂的制备方法，用Ru对MCM-41介孔分子筛进行了改性。使用表征技术，例如X射线粉末衍射，扫描电子显微镜，能量色散X射线显微分析，X射线荧光，XPS和氮吸附，研究了Ru–MCM-41合成催化剂的理化性质。肉桂醛的氢化用作测试反应，以评估Ru–MCM-41催化剂的催化性能。
