Graphical abstractPt/N-G nanocatalysts were successfully prepared, and investigated using various techniques. The results showed that the Pt nanoparticles were well dispersed on the N-G surfaces, with small particle sizes and narrow size distributions, ranging from 1 to 5 nm. Enhancements of the reactive surface area and specific peak current densities in methanol oxidation for the Pt/N-G catalysts, compared with the Pt/G catalyst, were obtained. The improved electrocatalytic activity can be ascribed to the optimized dispersion and smaller particle sizes induced by nitrogen doping.

Graphical abstractDensely packed graphene nanomesh-carbon nanotube hybrid (GNCN) film was prepared through a simple graphene etching process and subsequent vacuum-assisted filtration method. Based on its high surface area, fast ion diffusion and high film density, the GNCN film electrode shows ultra-high volumetric capacitance of 331Fcm−3 at 5mVs−1 in 6M KOH, which is among the highest values for graphene film reported in aqueous electrolyte, as well as excellent rate capability and outstanding cycling performance.

Graphical abstractA graphene foam-based flexible electrode provides a high electrical conductive network, interconnected ion diffusion channels, mechanical support and enough space for a large sulfur loading for Li-S batteries. Its areal capacity can reach 9.3mAhcm−2 at a high current density of 1500mAg−1 with an areal sulfur loading of 10.1mgcm−2, which is promising for flexible Li-S batteries with high energy density.
