Electrospun Pitch/Polyacrylonitrile composite carbon nanofibers as high performance anodes for lithium-ion batteries
关键字：Electrospinning ，Carbon materials ，Composite nanofibers ，Energy storage and conversion
A new kind of soft carbon and hard carbon composite nanofibers were fabricated from isotropic pitch and polyacrylonitrile via simple electrospinning followed by stabilization and carbonization. The obtained fibrous mat was directly used as anodes of lithium-ion batteries without binder added and current collector. The composite nanofibers electrodes display a large reversible capa...

05 Electrochemical characteristics of discrete, uniform, and monodispersed hollow mesoporous carbon spheres in double-layered supercapacitors
关键字：nanostructures, chemical vapor deposition, mesoporous materials, silica, supercapacitors
Core-shell‐structured mesoporous silica spheres were prepared by using n-octadecyltrimethoxysilane (C18TMS) as the surfactant. Hollow mesoporous carbon spheres with controllable diameters were fabricated from core-shell‐structured mesoporous silica sphere templates by chemical vapor deposition (CVD). By controlling the thickness of the silica shell, hollow carbon spheres (HCSs) with different di...

04 Effect of Cl/Ni molar ratio on the catalytic conversion of polypropylene into Cu-Ni/C composites and their application in catalyzing "Click" reaction
关键字：Carbon materials, Catalysis, Composites, Polypropylene
A one-pot approach to prepare Cu–Ni/C heterogeneous composites by carbonization of polypropylene (PP) using combined catalysts of Ni2O3 and CuCl was proposed. TEM, SEM, TGA and Raman measurements were performed to investigate the effects of Cl/Ni molar ratios on the yield and morphology of the resultant carbon materials. The yield of carbon materials in Cu–Ni/C first increased and then decreased...
