一种坚固耐用的新型电催化剂，具有超低的铂负载量、极强的抗中毒能力和高稳定性(见图)，显示出甲酸电氧化效率比商业铂/碳催化剂提高100倍以上。原位红外光谱表明，性能的大幅提高主要是通过利用Au团簇改变反应路径来实现的，同时也提高了稳定性。
A robust new electrocatalyst with ultralow Pt loading, great poisoning resistance, and high stability (see figure) shows an over 100-fold increase in the efficiency of formic acid electro-oxidation, compared with the commercial Pt/C catalyst. In situ IR spectroscopy proves that the greatly enhanced performance is mainly achieved by changing reaction pathways using Au clusters, which simultaneously improve the stability.
