Danthron (DT) with multi-electron redox centers as a novel organic electrochemically active material for supercapacitors has been decorated on reduced graphene oxide nanosheets (RGNs) via a facile one-step reflux method.
A one-step method to prepare reduced graphene oxide/PdxAuy/polypyrrole composites with good catalytic activity was introduced. The morphologies of alloy nanostructures could turn to be spherical, coral-like and porous cluster-like.
Sulfur- and nitrogen-co-doped carbon dots were synthesized by the one step hydrothermal treatment of pyritinol hydrochloride in the presence of graphene oxide, and could be used as an effective fluorescent probe for the detection of Hg2+.
