A supercapacitor is a device which can store electrical energy on conductive materials with a highly porous structure. Carbon-based electrochemical capacitors exhibit fast charge/discharge rate and high power density but limited by low energy density compared with lithium ion batteries. We used the self-assembly method to construct a three-dimensional graphene-based nanoporous carbon derived from...
A large scale 3D interconnected hierarchical porous carbon monolith was developed by a novel synthetic approach from the 2nd most abundant natural polymer, lignin. This newly derived carbon monolith possess desirable microstructure and high conductivity that enables the fabrication of a binder-/conductive additive-free thick electrode. The carbon monolith delivered simultaneously excellent areal/volumetric...
N-doped graphene oxide (NGO) thin film is synthesized by irradiation of graphene oxide (GO) thin film in NH3 atmosphere. NGO thin film obtained by irradiation of GO thin film for 60min has a high N-doping level of 12.69at.%, and the amino-like N dominates the doping with the level of 7.90at.%. The photoconductivity properties of NGO thin film under white-light illumination have been systematically...
Multi-walled carbon nanotubes (MWCNTs) were efficiently synthesized by catalytic combustion of polypropylene (PP) using nickel compounds (such as Ni 2 O 3 , NiO, Ni(OH) 2 and NiCO 3 ·2Ni(OH) 2 ) as catalysts in the presence of organic-modified montmorillonite (OMMT) at 630–830°C. Morphologies of the sample undergoing different combustion times were observed...
