博士研究生毕静磊论文“ Localized Surface Plasmon Enhanced Electrocatalytic Methanol Oxidation of AgPt Bimetallic Nanoparticles with Ultra-thin Shell ”被Chemical Communications 接收。该工作系统揭示了表面局域等离子体效应对AgPt双金属纳米球促进甲醇电化学催化氧化反应的影响机制。

The unique bimetallic nanostructures act as both the light absorber and catalytic active site simultaneously, and exhibit enhanced MOR activity in anode oxidation reaction of DMFCs in contrast to the conventional commercial catalysis. The LSPR-induced photothermal effects result in the increased local temperature of AgPt-BHNPs, significantly accelerating the MOR process. Moreover, the surface charge heterogeneity, which is caused by plasmon effects of Ag species, lead to the decrease of  the d-band centre character of Pt in AgPt-BHNPs, thus suppressing the absorption of CO during MOR process and enhancing the CO poisoning tolerance property of AgPt-BHNPs. As such, the work will be of general interests to a broad range of researchers in the field of electrocatalysis.
