【 摘 要 】

A convenient low cost approach to synthesize carbon nanotubes (CNTs) by chemical vapor deposition at atmospheric pressure is report. CNTs are grown directly on the nickel substrate without any extra catalyst to make the thermo-electrochemical cell (TEC) electrodes. The as-prepared CNT electrodes are first applied to make the TEC electrodes with the current density of 56 mA.m-2and the power density up to 1.24 W.m-2. The relative conversion efficiency of the TECs can reach 0.86%. The results suggest that the facile growth of CNTs under atmospheric pressure offers a promising approach for practical applications of the CNT-based TEC electrodes.
