Owing to the unique thermal transfer property, graphene attracts great attention as heat dissipation material. Many works have been devoted to increase thermal conductivity of graphene filled polymer composite by increasing the graphene loading. In this work, a novel composite was fabricated by rolling graphene sheets into vertically aligned graphene film (VAGF) and then penetrating liquid polydimethylsiloxane...
Low cost materials with high electrochemical catalytic activity for oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) are in urgent demand for energy storage and conversion devices. In this work, we propose a novel and environmentally-friendly approach to synthesize in situ a meso-porous MnOx/S doped graphitized carbon (MnOx/S-GC) hybrid with a specific surface area of 502.6m2g−1...
Oxygen evolution reaction (OER) is critical to many important energy conversion and storage processes. However, the kinetics of OER is typically sluggish, and conventional OER catalysts are scarce and expensive. Hence, inexpensive and effective catalysts that accelerate the OER kinetics and reduce the overpotential are urgently needed. In this paper, we reported multi-layer graphene-supported perovskite...
We reported on the facile synthesis of N-doped multilayer graphene (N-MLG) from milk powder that uses melamine as a nitrogen-doping source with Fe2+ ions as catalytic growth agents. We showed that milk powder could be used as a precursor for large-scale N-MLG synthesis through heat treatment at 1000°C under N2 atmosphere for 45–120min. In addition, heating time has a remarkable effect on N content...
Multi-wall carbon nanotubes (MWCNTs) were synthesized by detonation-assisted chemical vapor deposition using a series of rare earth (RE) oxides as catalysts. Energy dispersive X-ray spectroscopy, selected area electron diffraction and powder X-ray diffraction show that the catalysts, usually located outside the MWCNTs, have not been reduced, in sharp contrast to conventional catalysts in the form...
Graphene was synthesized by the detonation-assisted reduction of graphite oxide (GO) prepared by the modified Hummers method. Nitrogen-doped reduced GO (N-RGO) was obtained through an in situ nitrogen-doping during detonation. The morphology, elemental composition and structure of the N-RGO were characterized by TEM, SEM, IR, XPS, XRD and Raman spectroscopy. The catalytic activity of the N-RGO as...
