Abstract
The nitrogen-doped carbon embedded nanoporous TiO2 electrode is synthesized by a sol-gel technique assisted the amide condensation reaction for multifunction electrochromic energy storage device. By controlling the content of oleylamine (2.0 wt%), the nitrogen-doped carbon embedded nanoporous TiO2 film has the optimal surface nanoporous morphology (2.0OL-TiO2) and the excellent electrochromic energy storage properties, such as the high coloration efficiency (69.6 cm2 C−1), the short switching time (bleaching time of 4.7 s and coloration time of 5.6 s) and the large specific capacitance (127.5 F g−1) at a current density of 2 A g−1. These fascinating properties are mainly attributed to the optimal surface nanoporous morphology which can improve the electrochemical activity. Here, the nanoporous structure is generated by the evaporation of water molecules which are formed in the amide condensation reaction. In addition, the nitrogen-doped carbon leads to an enhancement in electrical conductivity during the multimeric amide condensation reaction. The results show that the nitrogen-doped carbon can provide adequate ion and electron transport pathways. Therefore, it is worth believing that the research is of great significance to realize the electrode design of multifunctional electrochromic energy storage device.
