ChemInform Abstract: Transition‐Metal‐Catalyzed Direct Addition of Unactivated C‐H Bonds to Polar Unsaturated Bonds

Catalytic activities of oxidized Pt-Pd/Al2O3 and reduced Pt-Pd/Al2O3 catalysts,oxidized Pt-Rh-Pd/Al2O3 and reduced Pt-Rh-Pd/Al2O3 catalysts were studied with flow-system micro reactor.All these catalysts were characterized by TPD,XRD and TPR and their catalytic mechanisms were discussed.The results showed that oxidation activity of oxidized Pt-Pd/Al2O3 catalyst is superior to that of reduced Pt-Pd/Al2O3 catalyst,and they have the same catalytic mechanism.The oxidation activity of oxidized Pt-Rh-Pd/Al2O3 catalyst is not as good as that of reduced Pt-Rh-Pd/Al2O3 catalyst,which is attributed to their different catalytic mechanisms.Noble metals combined with oxygen are harmful to the reduction activities.

Effect of Si/Al Ratio on the Performance of Mo/ZSM-5 Catalysts for Selective Catalytic Reduction of NO

Journal of Molecular Catalysis(China) (2005)

Wei Huang

Three Mo/ZSM-5 catalysts from different HZSM-5 were prepared by wet impregnation method and their catalytic activity has also been tested. The results showed that the catalytic performance for NO selective catalytic reduction over 1# catalyst which has the lowest value of Si/Al ratio is much better than 2# and 3# catalysts at the same experiment condition, its NO conversion reaches 94% at 530 ℃, while only 48% and 41% was given by 2# and 3# catalyst. To understand the effect of different Si/Al ratio on the activity of Mo/ZSM-5, the bulk-phase and surface compositions of the catalysts were determined by XRD, XPS and NO-TPD respectively. The results showed that Mo/ZSM-5 catalysts with different Si/Al ratio not only exhibits an obvious difference of catalytic activity for selective catalytic reduction of NO, but also results in the distinction of bulk phase structure and surface properties. Especially the different surface Mo contents may cause the difference in activity of three Mo/ZSM-5 catalysts.
