Abstract: Photocatalyst hydrogen storage alloys(PHSA) with different photocatalyst contents were synthesized by mechanical blend method. The effects of the photocatalyst on the electrochemical performance of the PHSA were studied. The results indicate that the PHSA electrodes show better activation performance when UV irradiation is present. The high rate discharge performance as well as cycle performance is improved compared with that of the AB5 alloys. The PHSA shows the best performance when the photocatalyst content is 20%.
Key words: photocatalyst; hydrogen storage alloys; electrochemical performance
