چکیده انگلیسی
Highly conductive porous Na-embedded carbon nanowalls (Na@C), which were recently invented, have exhibited excellent performance for dye-sensitized solar cells and electric double-layer capacitors. In this work, Na@C was demonstrated as an excellent electrode material for capacitive deionization (CDI). In a three-electrode configuration system, the specific capacity of the Na@C electrodes can achieve 306.4â¯F/g at current density of 0.2 A/g in 1â¯M NaCl, which is higher than that (235.2â¯F/g) of activated carbon (AC) electrodes. Furthermore, a high electrosorption capacity of 8.75â¯mgâ¯gâ1 in 100â¯mg/L NaCl was obtained with the Na@C electrodes in a batch-mode capacitive deionization cell. It exceeds the electrosorption capacity (4.08â¯mgâ¯gâ1) of AC electrodes. The Na@C electrode also showed a promising cycle stability. The excellent performance of Na@C electrode for capacitive deionization (CDI) can be attributed to its high electrical conductivity and large accessible surface area.
