The three-dimensional (3D) hybrid aerogels built from graphene and polypyrrole-derived nitrogen-doped carbon nanotubes (G-NCNTs) are synthesized by facile hydrothermal and heat treatment process using graphite oxide (GO) and polypyrrole nanotubes (PNTs) as precursors. The 3D G-NCNTs hybrid aerogels, in which the NCNTs are dispersed homogeneously in the graphene sheets, are designed to efficiently...
Nitrogen-doped carbon nanotubes (CNx-NTs), platinum (Pt)-based catalysts supports, were prepared by pyrolysis of polypyrrole nanotubes (PPy-NTs), which were synthesized using a self-degraded template method. The morphology, structure and physicochemical properties of CNx-NTs supports and Pt/CNx-NTs catalysts were investigated by scanning electron microscope, Brunauer-Emmett-Teller surface area, transmission...
Graphitic carbon nitride (g-C3N4) has been demonstrated as an advanced support material for Pt nanoparticles (NPs) due to its excellent stability and abundant Lewis acid for anchoring metal NPs. However, its non-conductive nature and low surface areas still impede its application in electrochemical fields. Herein, a π–π stacking method is presented to prepare graphene/ultrathin g-C3N4 nanosheets composite...
A novel nitrogen-doped carbon material with honeycomb-like mesoporous structure was synthesized via carbonization of polyaniline under template and acted as support for the Pt catalyst. Pyrolysis temperature plays a significant role in enhancing electrochemical performance of Pt/mesoporous nitrogen-doped carbon (Pt/MNC) catalyst. Considering comprehensively electrocatalytic activity and stability...
