Electrosorption of ions from aqueous solutions with carbon nanotubes and nanofibres (CNTs-CNFs) film electrodes has been demonstrated. The cost-effective, large area CNTs-CNFs film was synthesised on graphite substrate by low pressure and low temperature thermal chemical vapor deposition (CVD). Successful removal of Cu2+ from water by electrosorption of CNTs-CNFs films was achieved. The electrosorption...
Multi-wall carbon nanotubes (MWNTs) had been synthesized by catalytic chemical vapor deposition of acetylene over Fe loaded mesoporous silica. The as-grown MWNTs were purified by a two-step purification procedure involving acid washing and oxidation in diluted air, and characterized using powder X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), thermo...
In this work, carbon nanotubes and carbon nanofibres (CNTs-CNFs) composite film was synthesized by low pressure thermal chemical vapor deposition. CNTs-CNFs film was characterized by scanning electron microscopy and Raman spectroscopy. The effect of different growth temperature on the morphology of CNTs-CNFs and electrosorption of NaCl solution by CNTs-CNFs film grown at 550degC, 600degC, 650degC...
Single walled carbon nanotubes (SWCNT) as well as oxygen and nitrogen adsorption are studied by density function and discrete variational (DFT-DVM) method, one of the first principle calculation methods. Several models with difference lengths and calibers are studied to discuss the length and section of SWCNT that affects the properties. Different types of adsorption models are optimized based on...
