Additionally, they claimed that the graphene-cobalt catalyst remained more consistent than platinum. They specified that platinum degraded during the experimentation, faster than the new catalyst. The event proved that the combination of graphene and cobalt could endure more exertion than platinum.
The researchers also mentioned that both materials performed differently after 17 hours of experimentation, compared to their initial execution. According to Sun, the graphene-cobalt catalyst degraded its performance by only 30%, while platinum faded for more than 10% of the other material.
Therefore, graphene-cobalt maintained 70% of its initial capabilities at the latter part of the testing, outperforming the power of platinum by 60%
