摘要：Ultrathin MoO3nanocrystals were assembled on 3D graphene oxide frameworks via a hydrothermal reaction forming a layered structure by oxygen-bonding interactions at the interface. The structure and morphology of the resulting MoO3-GAs hybrids were characterized by a range of experimental tools including atomic force microscopy, scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, infrared and Raman spectroscopy. Because of abundant exposed active sites of the ultrathin MoO3and rapid ion diffusion and electron transport of 3D graphene frameworks, the resulting MoO3-GAs hybrids possess the highest specific capacitances and excellent cycling stability in both aqueous (527Fg-1at the current density of 1.0Ag-1, 100% retention after 10,000 cycles) and solid electrolytes (373Fg-1at 1.0Ag-1, 100% retention after 5,000 cycles) among leading literature results of similar systems.
