Rational design ternary platinum based electrocatalysts for effective methanol oxidation reaction

Hao Tian et al.

Summary: This study develops a method to synthesize two-dimensional ternary PtBiM nanoplates, which exhibit excellent catalytic activity and durability in the methanol oxidation reaction (MOR). Among them, Pt3Bi3Zn nanoplates show higher activity and stability compared with PtBi nanoplates, PtRu/C catalyst, and Pt/C catalyst. This is attributed to the modulated electronic structure of Pt in PtBi nanoplates by the addition of Zn, leading to weakened interaction with adsorbed species like CO. In addition, the absorbed OH on the surface of Zn accelerates the removal of CO on adjacent Pt atoms, resulting in enhanced activity and anti-poisoning performance of the Pt3Bi3Zn catalyst.
