Electrosorption of NaCl by Carbon Nanotubes and Carbon Nanofibres Composite Film Grown at Different Temperatures

摘要

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 550°C, 600°C, 650°C have been investigated, respectively. The result showed that the desalination efficiency decreased with the increasing growth temperature. The optimal adsorption capacity was achieved by CNTs-CNFs film grown at 550°C.
