A new bismuth-based polymer, [Hbpe][Bi(Hpydc)(2)(pydc)]H2O (H(2)pydc=pyridine-2,5-dicarboxylic acid, bpe=trans-bis(4-pyridyl) ethylene) has been hydrothermally synthesized. Transient photocurrent response and electrochemical impedance spectroscopy studies indicate that the synthesized polymer with efficient charge separation and transportation can be used as a potential photocatalyst. So we use it for the degradation of rhodamine B (RhB) dye wastewater under visible light. The comparative study on commercial Bi2O3 shows [Hbpe][Bi(Hpydc)(2)(pydc)]center dot H2O has the higher photocatalytic performance, with the degradation rate of 97% and 2% within 100 min for [Hbpe][Bi(Hpydc)(2)(PYdc)center dot H2O and commercial Bi2O3 respectively. Additionally, the five cycle reproducibility results of [Hbpe][Bi(Hpydc)(2)pydc)]center dot H2O implies that it can be used as a stable photocatalyst.
