Abstract

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 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 550degC.
