title: Could carbonaceous impurities in reduced graphenes be responsible for some of their extraordinary electrocatalytic activities?
abstract: Thermally and chemically reduced graphene materials contain significant amounts of carbonaceous impurities that are similar in structure to amorphous carbon. Herein, we show that the claimed electrocatalytic activities of these materials for the oxidation of NADH, acetaminophen, and hydroquinone are mainly due to the presence of carbonaceous impurities.
