摘要
随着半导体催化技术的进步,基于共轭高分子应用的改性催化材料受到广泛的关注,与其它半导体光催化剂相比,窄带隙半导体Fe_(2)O_(3)具有较优异的可见光光催化性能,但Fe_(2)O_(3)光生电子--空穴复合率高限制了其推广应用。本团队运用原位聚合--热转化两步合成了α-Fe_(2)O_(3)/聚糠醇纳米复合材料,通过TG、TEM、UV-Vis等手段进行了表征并研究了其光催化活性,展望了该材料未来在污水处理方面的应用前景。
In recent years,conjugate polymer modified semiconductor photocatalysis has attracted extensive attention from researchers.Compared with other semiconductor photocatalysts,narrow-band gap semiconductor Fe_(2)O_(3)has better visible photocatalytic performance,but its high photoelectron-hole recombination rate limits its application.Theα-Fe_(2)O_(3)/polyfurfuryl alcohol nanocomposites were synthesized by in-situ polymerization and thermal transformation.The photocatalytic activity ofα-Fe_(2)O_(3)/polyfurfuryl alcohol nanocomposites was characterized by TG,TEM,UV-Vis and other means,and the application prospect of the materials in wastewater treatment was prospected.
