(Phys.org)—Fuel cells require a catalyst for the oxygen reduction reaction. One type of catalyst is nitrogen-doped graphene-oxide nanosheets. Graphene-oxide nanosheets are easily functionalized with other atoms such as ...
(Phys.org)—Single sheets of graphene, a curious material only 1 atom thick, are 100 times more chemically reactive than double or triple sheets, Stanford scientists say in a new paper published online Jan. 17 in ACS Nano. ...
