Water-soluble polymer exfoliated graphene: As catalyst support and sensor. The journal of physical chemistry B, 117(18), 5606-5613. | Series/Report no.: | The journal of physical chemistry B | Abstract: | In this paper, we obtained various water-soluble polymer functionalized graphene in dimethyl sulfoxide under ultrasonication. The atomic force microscope analysis and control experiment shows the water-soluble polymer is the crucial part to help solvent molecules separate interlayer. Such polymer/graphene exhibits high conductivity and tunable surface property, as confirmed by the selected area electron diffraction and Raman and electrochemical impedance spectroscopy. As a result, a catalyst based on polyvinyl pyrrolidone (PVP)/graphene shows better methanol oxidation performance than that based on PVP/reduced graphene oxide. By changing to another polymer, poly(4-vinylpyridine)/graphene shows a stable and reversible response to pH, and demonstrates its potential for sensor application. | URI: | https://hdl.handle.net/10356/101112 http://hdl.handle.net/10220/16745 |
