Researchers report unexpected catalytic activity of nanorippled graphene

Researchers from the University of Manchester in the UK, Wuhan University and Tsinghua University in China and Kansas State University in the U.S have found that nanoripples in graphene can make it a strong catalyst, contrary to predictions that the carbon sheet is as chemically inert as bulk graphite.   Led by Professor Andre Geim from the National Graphene Institute (NGI), the researchers found that nanorippled graphene can accelerate hydrogen splitting as well as the best metallic-based catalysts. The findings were unexpected, as previous research predicted that graphene would be as chemically inert as the bulk graphite from which it is obtained. The effect is likely to be present in all two-dimensional materials, which inherently are all non-flat.
