Graphene and chicken poop
A recent article in C&EN entitled chicken poop improves graphene catalysts highlights the perspective by Prof. Martin Pumera: " Will Any Crap We Put into Graphene Increase Its Electrocatalytic Effect?" published in ACS NANO. Prof. Martin emphasis that the scientific resources should be more utilized towards understanding the mechanistic aspects of doping rather than increasing the number of papers with different dopants on graphene.
