摘要
以海藻酸钠(SA)气凝胶为基体,通过原位生长法将金属有机骨架材料NH_(2)-MIL-88B(NM88B)引入气凝胶三维骨架结构中,构建了具有光催化降解性能的复合气凝胶SA/NH_(2)-MIL-88B(NM88B)。采用SEM、FTIR、XPS及XRD等对SA/NM88B复合气凝胶的表面形貌、结构组成及晶型结构进行了一系列表征,同时,探究可见光下其对对染料(亚甲基蓝,MB)及抗生素(盐酸四环素,TC-HCl)废水催化降解的性能。
Based on the sodium alginate(SA)aerogel,the composite aerogel SA/NH_(2)-MIL-88B(NM88B)with photocatalytic degradation performance was constructed by in-situ growth of NH_(2)-MIL-88B(NM88B)on SA aerogel matrix.The surface morphology,structural composition and crystal structure of SA/NM88B composite aerogels were characterized by SEM,FTIR,XPS and XRD.Meanwhile,the catalytic degradation performance of SA/NM88B composite aerogel towards dye(methylene blue,MB)and antibiotic(tetracycline hydrochloride,TC-HCl)wastewater was investigated under visible light irradiation.
