Ultralow-Platinum-Loading High-Performance Nanoporous Electrocatalysts with Nanoengineered Surface Structures

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...

Zusammenfassung: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.
