Graphene, with tiny ripples on its surface, can split hydrogen 100 times better than known chemical catalysts. It could be used to develop more effective hydrogen fuel cells and make many industrial processes more efficient.
A one-atom-thick layer of carbon, graphene is essentially a slice of graphite. The latter are very unreactive compounds due to their strong carbon bonds.
But with Andre Geim of the University of Manchester in England…
