Waste semi-coke powder generated in semi-coke production and transportation was doped with 8mass% boron by a high temperature treatment at 2300°C. Results indicate that the doping overcomes the shortcomings of low coulombic efficiency, short cycle life, and there are no charge and discharge platforms due to a high content (15 mass%) of impurity in the raw materials. The first discharge capacity is...
A simple process to synthesize three-dimensional molybdenum disulfide-graphene monolithic catalysts (3D-MoS2-G) was developed. 3D-MoS2-G hybrid monoliths were fabricated by a combined hydrothermal self-assembly and freeze-drying treatment, in which ammonium tetrathiomolybdate and graphite oxide were used as starting materials. The structure and morphology of the samples were characterized by X-ray...
We have developed a method that would allow for the fabrication of carbon aerogel (CA) spheres. The inverse phase suspension polymerization of resorcinol and formaldehyde monomers with Na 2 CO 3 as a catalyst followed by supercritical drying was explored. The effects of the chemical formulation and processing procedures and the conditions of the structures of organic and related carbon...
