title: Highly qualified reduced graphene oxides: the best chemical reduction.
abstract: We report new step-by-step reduction methods by alternating two different reducing reagents with the order of hydrazine with NH(3) (NH)/HI in acetic acid (HI) and the reverse order (HI/NH) to understand nitrogen incorporation and removal or reduction for providing highly qualified reduced graphene oxides (rGOs).
