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...
Carbon nanotubes (CNTs) films were synthesized at low pressure using nickel as catalyst by thermal chemical vapor deposition with hydrogen-acetylene mixture. The Raman characteristics and morphological features of CNTs at different substrate temperatures were investigated. The variation of CNTs morphological feature mainly depends on the substrate temperatures. In the low temperature range (450-550degC),...
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...
Two different carbon nanotubes (CNTs) were synthesized by thermal chemical vapor deposition (CVD) system through two different apparatuses. Uniform deposition of CNTs on glass substrate was observed through optimizing parameters in the process of electrophoresis by scanning electron microscopy (SEM). The field emission properties were tested in the diode-type construction with the cathode-anode gap...
β-SiC thin films were deposited on silicon substrates by hot filament chemical vapour deposition from methane diluted with hydrogen. Under deposition conditions with a CH 4 :H 2 ratio of 0.5%, filament temperature of 2200-2400 °C, gas pressure of 10 kPa and distance between filament and substrate of 2-8 mm, if the substrate temperature is between 700 and 1000 °C, diamond films were...
Using a conventional hot-filament chemical vapor deposition system, diamond crystals and films were deposited on diamond-like carbon (DLC) films which were synthesized from a [C 6 H 5 C] n polymer on silicon substrates under a temperature of 1000 °C in an argon atmosphere. The nucleation density of the diamond on DLC-Si substrates was estimated to be about 10 8 to 10...
