| 摘 要： | 以Fe(NO3)3·9H2O和糠醛(FD)为原料,通过聚合-热转化两步法制备了Fe2O3/聚糠醛(PFD)纳米复合材料,用TEM、XRD、XPS和UV-Vis等技术对其尺寸、结构及吸光特性等进行了表征。在自然光、室温条件下,以亚甲基蓝(MB)溶液的催化脱色降解为模型反应,考察了其光催化性能以及热转化温度对催化性能的影响。结果表明,利用该法可以得到纳米级的、相间以强相互相用结合的有机-无机复合材料Fe2O3/PFD,该纳米材料对紫外-可见区的全程光波有强的吸收;热转化条件对复合材料的结构、催化性能等有很大影响,在300℃下处理35min所得的纳米复合材料在自然光条件下具有最佳的催化性能,25min即可使MB溶液完全脱色,并且重复使用3次仍可使MB溶液的脱色率保持在75.0%以上。而在相同条件下,纳米Fe2O3仅能使MB的脱色率达到5.8%。
