摘要
在马弗炉中高温热解三聚氰胺和尿素制备石墨相碳化氮,利用水热合成出基于咪唑(4,5-f)-1,10-邻菲罗啉的Ni配合物,所得配合物到C3N4上,采用X射线衍射光谱(XRD)、扫描电子显微镜(SEM)对样品进行了表征,研究了甲基橙浓度、负载量、pH值在可见光下对降解效率的影响,结果表明:在pH=3的条件下,加入5%负载量的Ni-C3N4降解浓度为50mg·L^-1的甲基橙溶液,降解90min,其降解效果最好。
Graphite-phase nitrogen carbide was prepared by high-temperature pyrolysis of melamine and urea in a muffle furnace.Ni complex based on imidazole(4,5-f)-1,10-o-phenanthroline was prepared by hydrothermal synthesis,the complex was doped to C3N4.The samples were characterized by X-ray diffraction spectroscopy(XRD)and scanning electron microscopy(SEM).The effect of methyl orange concentration,loading and pH on degradation efficiency under visible light was studied.The results showed that,under the conditions of pH=3,adding Ni-C3N4 with 5% loading,50 mg·L^-1 methyl orange solution was degraded for 90 min,the degradation effect was the best.
