Polyimide Photocatalytic Material for Photocatalytic Conversion of Benzylamine

The sulfur-doped polyimides were prepared at different temperatures by one-pot hot polymerization method. Phase analysis by SEM, XRD and FT-IR showed that the synthesized polyimides had good structure and crystallinity. The sulfur-doped polyimides were prepared at different temperatures by one-pot hot polymerization method. Phase analysis by SEM, XRD and FT-IR showed that the synthesized polyimides had good structure and crystallinity. The results of UV diffuse reflection, AC impedance, fluorescence spectrum and photocurrent test show that the polyimide synthesized at 325°C has better photoelectric performance. It has been applied to the photocatalytic benzylamine coupling experiment and has good yield and selectivity under 8.5 hours of illumination.
