摘要: Abstract In this paper, a facile and scalable aqueous process including mild oxidative intercalation, microwave exfoliation, ultrasonication, drying Ar-annealing is developed to synthesize the water-soluble microwave-exfoliated graphene (MEG)/platinum nanoparticles (PtNPs) composite, which has relative low defect level can be readily dispersed in deionized water without adding surfactants. This cost synthesis method applicable many systems, such as supercapacitors, thermal storage, lithium battery Dye-sensitized solar cells (DSSCs). An efficiency of 6.69% for MEG/PtNPs composite deposited on ITO PEN flexible counter electrode (CE) DSSCs been obtained, higher than control device made by PVP-Pt CE.
