Abstract
Abstract A new ferrocene-based porous organic polymer (named FcTz-POP) was rationally designed and synthesized. With abundant ferrocene and triazine blocks, FcTz-POP is a versatile functional material that with porous structure, high electron density and excellent stability. UV–Vis absorption spectra showed FcTz-POP exhibited a significant coverage of the solar irradiance spectrum. Photocatalytic experiments proved that FcTz-POP was highly efficient for methylene blue (MB) degradation under visible light irradiation at neutral pH. The effects of the initial MB, H2O2 concentrations, pH value and ion strength on MB degradation were studied. The catalytic mechanism of FcTz-POP was also proposed. In addition, FcTz-POP possessed an outstanding and reversible adsorption ability for iodine vapor with the uptake value of 2.64 g g−1 because of the strong charge-transfer interaction between the polymer and iodine molecules. These results may provide a guidance for the design of novel POPs for photocatalytic degradation of organic dyes and harmful volatile substances capture.
