Abstract

Polyacrylonitrile (PAN)/polymetalliciron oxides used as photocatalysts for water splitting were prepared by coprecipitation and impregnation methods. Fourier transform infrared spectroscopy (FTIR) showed that the cyclic structures were formed in the PAN chains after heat treatment. The functional groups of PAN showed strong interactions with metal ions. According to X-ray diffraction (XRD) characterizations, iron oxides were Fe3O4 cubic crystalline in the photocatalysts, and other metal ions existed as their relative oxides. Photocatalysis for water splitting into H2 presented efficient activity and the optimum rate reached 714.3 μmol/(g·h).

Key words： iron oxides; polyacrylonitrile (PAN); polymetallic; visiblelight photocatalysis; water splitting
