Conclusion
In this paper, we report a new 1D coordination polymer based on bismuth and H2pydc, and examine its thermal stability and photo- electric properties. UV/Vis diffuse measurement indicates that this complex may be responsive to the visible light and possess the potential for photocatalytic reactions, which is further confirmed by the decom- position studies of organic dye (RhB) aqueous solutions under the white LED irradiation. Additionally, comparative study on commercial
Bi2O3 shows that the synthesized polymer has higher photocatalytic performance, which is owning to the efficient charge separation and transportation as evaluated by the electrochemical measurements. Finally, repeated experiment also displays the reproducibility of photocatalytic activity for this complex. So the water-insoluble and thermal stable bismuth-based coordination polymer with high photo- catalytic activity and reproducibility under visible light irradiation implies that it can be used as a stable and efficient photocatalyst for the treatment of dye wastewater in practice.
