Abstract:
The highly active inverse ZrO2/Cu catalyst used in methanol steam reforming reaction was confirmed by XRD and HRTEM. Control experiments and characterization results consistently differentiated surface and interfacial hydroxyl groups. For the catalyst enriched in interfacial OH, the reaction preferentially proceeded through the formate pathway. However, for the catalyst enriched in surface OH, methyl formate pathway preferentially existed on its surface. This work reveals the role of OH plays in the methanol steam reforming reaction, preliminarily establishing foundation for the investigation of H2O-participated reactions.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
