摘要:
为了增加多孔氮化硼(PBN)的再生性能,采用水热法成功地制备了α相氧化铁/PBN(α-Fe2O3/PBN)复合净水材料。研究了水热反应和再生过程对α-Fe2O3/PBN复合材料的晶体结构、比表面积和吸附性能的影响。实验结果证实,负载在PBN表面的α-Fe2O3颗粒在过氧化氢的辅助下对吸附在其表面的亚甲基蓝(MB)具有优异的协同催化降解活性。经过6次吸附-再生循环后,α-Fe2O3/PBN复合材料对水中MB的移除效率保持了初始的93.5%,而在相同实验条件下,PBN的移除效率仅为初始的11.8%。同时研究了α-Fe2O3/PBN复合材料的再生机理。
Abstract:
To enhance regeneration performance of porous boron nitride (PBN),the hematite/PBN(α-Fe2O3/PBN) composites were successfully synthesized with the hydrothermal method. The effects of hydrothermal reaction and regeneration process on the crystal structure,specific surface area and adsorption performance of the α-Fe2O3/PBN composites were investigated. The results demonstrate that the hematite particles supported on PBN exhibit excellent synergistic catalytic activity for degradation of methylene blue (MB) on the surfaces with the assistance of hydrogen peroxide. 93.5% of the MB removal efficiency in the α-Fe2O3/PBN composites is remained unchanged after six adsorption-regeneration cycles,while the removal efficiency of PBN is only 11.8% under the same condition. Finally,the regeneration mechanism of the α-Fe2O3/PBN composites was also studied.
