摘要 随着科技不断进步,环境污染问题日益严重。本工作制备了新型氮化碳/聚吡咯复合光催化剂。通过FT-IR、SEM等方法对复合催化剂的结构进行可表征,并利用UV-Vis DRS研究其光学性质,通过罗丹明B作为虚拟污染物评价了其光催化活性。研究表明氮化碳/聚吡咯复合光催化剂对染料罗丹明B具有较高的催化活性,且聚吡咯含量为1wt%时,复合光催化剂的催化活性最高。PL光谱进一步证实引入聚吡咯可有效减少电子空穴对的复合,从而可显著提高复合催化剂的光催化效率。 As the fast development of science and technology, the environmental pollution has become increasingly serious. Novel carbon nitrile/polypyrrole composite catalysts were prepared, and the structures of the new obtained catalysts were characterized by FT-IR and SEM. The optical properties were investigated by UV-Vis DRS. In addition, Rhodamine B was used as a virtual pollution to evaluate the photocatalytic activity. The results showed that the carbon nitrile/polypyrrole composite photocatalysts had high catalytic activity for dye Rhodamine B, and the pohocatalytic activity reached the highest as the content of polypyrrole was 1wt%. Moreover, PL spectra further confirmed that the introduction of polypyrrole can effectively reduce the electron hole complex, which can significantly improve the photocatalytic efficiency of the composite catalysts.
