| Abstract: | Cu/SiO 2 catalysts modified by Cr 2O 3 and MoO 3 have been characterized with a continuous fixed bed reactor. The influence of Cr 2O 3 and MoO 3 on the surface properties and active site of catalysts has also been studied with TPR, XPS and XRD. The results show that catalytic properties of catalysts modified by Cr and Mo are improved remarkably and Cr 2O 3 and MoO 3 in the catalysts have the property of donating electrons towards Cu particles. Adding proper amounts of Cr, Mo to catalysts can increase the dispersity of Cu particles and the stability of catalysts. |
