摘要
本文通过水热法制备二氧化钛纳米管(TiO2NT),并用制备的TiO2NT对碱性电解水制氢装置的镍片阳极进行修饰,在电解水的基础上,通过光催化与电解过程的耦合,提出并实现了光催化辅助电解水制氢过程。通过XRD、UV-Vis、FE-SEM、AFM和光催化辅助电解水制氢等方法对试样的结构和性能进行了表征和测试。结果表明,在紫外光照条件下,用TiO2NT修饰镍片阳极的光催化辅助电解水过程的产氢速率比单纯电解水提高了61%。
TiO2 nanotubes were coated onto Ni anodes assisted by photocatalysis （TiO2NT） were successfully synthesized by hydrothermal method. The TiO2 nanotubes for water electrolysis. A new hydrogen generation process, called as water electrolysis （WEAP）, was proposed based on the coupling of water electrolysis with photocatalytic hydrogen evolution. The samples were characterized by X-ray diffraction （XRD）, UV-Vis absorption spectroscope, field emission scanning electron microscope （FESEM）, atomic force microscope （AFM） and WEAP measurement. The results showed that the rate of hydrogen generation increased by 61% in WEAP with the anode modified with TiO2NT in comparison with that in sole water electrolysis with unmodified Ni anode.
