Effect of acetylene flow rate on electrosorption capacity of carbon nanotube and nanofiber composite film electrodes

Electrosorption of carbon nanotube and nanofiber (CNT-CNF) composite film electrodes was studied as a new desalination technology. The CNT-CNF composite film electrodes were grown on nickel sheets by low pressure thermal chemical vapor deposition. Different growth conditions at different acetylene flow rates of CNT-CNF composite film electrodes have been performed to obtain different crystallinities. The electrosorption experiments and Raman spectra, analysis show the successful removal of ions with CNT-CNF composite film electrodes, depending on the optimal degree of crystalline perfection. In our work, optimal electrosorption was realized for the CNT-CNF composite film electrodes growing at 550° C with the acetylene and hydrogen flow rates of 30 and 200 seem.
