Capacitive deionization (CDI) has attracted attention as low energy consumption and environmental friendly desalination technique, because it can be conducted at low voltages without secondary waste. In this work, we have synthesized carbon with ultrathin metal oxide layer by atomic layer deposition (ALD) technique and applied to CDI electrodes. It was identified from TEM, XRD, BET and XPS that the carbon was coated successfully by means of ALD method. In conclusion, carbon electrodes which was coated by ultrathin metal oxide with high dielectric and hydrophilic properties maintaining its high surface area shows potential for CDI electrode material more effective than previous carbon electrode in CDI system. |
