Platinum as a catalyst is expensive, and it degrades over time, but it works great in many applications especially in hydrogen fuel cells. A Brown University chemist team has engineered a cheaper and more durable catalyst using graphene, cobalt, and cobalt-oxide – perhaps the best non platinum catalyst so far.  The team’s paper has been […]

Researchers at the University of Cambridge have produced hydrogen from water using a newly designed and inexpensive cobalt catalyst.  It’s noteworthy because the cobalt catalyst will work in conditions useful to industry.  The catalyst uses simple fresh water, tolerates oxygen in the atmosphere and runs at room temperature. These attributes set up respectable “Faradaic efficiencies” […]
