吸附原子电催化机理的研究——铂单晶(100)晶面上Pb、Cd吸附原子在甲酸电氧化中的助催化特性

In this work a modified adsorption method was used to form firstly a saturated Cd or Pb adlayer on platinum single crystal (100) surface, then its surface structure, the electrochemical stability and the desorption-readsorption CV properties were studied. The HCOOH oxidation has been used as a probe to determine the electrocatalytic propertics of Pt (100) with different surface concentration of Cd or Pb adatoms. The results show that Cd adatoms on Pt(100) inhibit both HCOOH dissociation adsorption (to form poisoning intermediates) and HCOOH oxidation via the reactive intermediate, and that Pb adatoms on Pt(100) inhibit only HCOOH disociation adsorption but catalyse HCOOH oxidation via the reactive intermediate, in this case the more Pb adatoms on Pt(100), the higher te catalytic effect. The highest enhanced catalytic effet has been found with the saturated Pb adlayer on Pt(100) (the coverage of Pb, calibrated by hydrogen adsorption, is then equal to 1.0), i.e. with a surface structure of C(2×2)-bridged Pb. The difference of influence to the hydrogen adsorption-desorption process and the different catalytic effect on HCOOH oxidation of Cd and Pb adatoms on Pt(100) were attributed to the intrinsic properties of Cd and Pd elements and also to their interaction with Pt(100). This results indicate that the electrocatalytic mechanism of Cd and Pb adatom on Pt(100) depends on the geometrical surface structure effect and, more importantly, on the electro structure effect during the interaction of adatoms with Pt(100) surface atoms.

Zr柱撑蒙脱土上负载稀土铈及铜铈催化剂的制备与表征

The Zr-pillaraed montmorillonite supported Ce and Cu-Ce catalysts were prepared by impregnation method. The performance of the catalysts was evaluated via the catalytic oxidation of volatile organic compounds (acetone, ethyl acetate, and toluene). The results showed that after supporting with Ce and Cu-Ce, the catalysts had a better reducibility. Moreover, the surface areas of the samples were increased. In addition，it was found that the Zr-pillared montmorillonite supported Cu-Ce catalysts had a higher activity and the reaction temperature decreased by 150～200 ℃ compared with the sample without Cu-Ce modification.
