摘要:
为了提高石墨相氮化碳(g-C-3N-4)的光催化活性并实现其回收再利用,首先制备掺Br氮化碳,再将其与纤维素复合,制备具有宏观三维多孔结构的掺Br氮化碳纤维素复合材料,研究其对亚甲基蓝(MB)的光催化活性。研究结果表明:制备得到的掺Br氮化碳纤维素复合材料具有良好的三维多孔结构,掺Br氮化碳很好地负载于复合材料表面及孔壁;掺Br氮化碳纤维素复合材料具还展现出较好的力学性能,当压缩应变为80%时,压缩应力达到207 kPa。掺Br氮化碳纤维素复合材料能够在160 min光照时间内降解98%的亚甲基蓝,优于掺Br氮化碳;在H-2O-2辅助下,其降解效率在120 min能达到99.5%。宏观三维的掺Br氮化碳纤维素复合材料极易回收再利用,经4次循环,其对亚甲基蓝的光催化效率仍高于85%。研究结果对于实现宏观三维掺Br氮化碳纤维素复合材料对规模化水污染治理具有一定的参考意义。
