Group at CAS Lanzhou Institute of Chemical Physics prepares graphene supported anode catalysts for direct methanol fuel cells
The group has developed graphene supported dendritic PtNi bimetallic catalysts using Ni nanopaticles as the seeds and reducing agent. The as-made d-PtNi/G catalyst shows very large electrochemical active area (ECSA) and excellent electrochemical activity and stability toward methanol oxidation. Its electrochemical activity is much higher than those of the commercial Pt/C and PtRu/C catalysts for […]
