摘　　要：以C_(3)H_(6)N_(6)·2H_(3)BO_(3)为前驱体和纳米Fe_(2)O_(3)粉末为原料,通过热处理制备了一种BN/Fe复合材料。通过X射线衍射分析,扫描电子显微镜、透射电子显微镜、漫反射光谱等对合成的BN/Fe光催化剂进行表征,研究了其相组成、微结构和光催化性能。Fe_(2)O_(3)粉末在热处理下被还原为Fe纳米颗粒,合成了多孔结构的BN/Fe复合材料。在可见光照射下B4材料对MO的光降解活性最好,45 min内可快速降解99.3%的MO。Using C_(3)H_(6)N_(6)·2H_(3)BO_(3)as precursor and nano Fe_(2)O_(3)powder as raw materials,a BN/Fe composite is prepared by heat treatment.The synthesized BN/Fe photocatalyst is characterized by X-ray diffraction analysis,scanning electron microscopy,transmission electron microscopy and diffuse reflectance spectroscopy to study its phase composition,microstructure and photocatalytic performance.The Fe_(2)O_(3)powder is reduced to Fe nanoparticles under heat treatment.Then,BN/Fe composites with porous structure are synthesized.B4 material has the best photodegradation activity to MO under visible light irradiation and can rapidly degrade 99.3%MO in 45 minutes.
