| 摘 要： | 在混合溶剂体系中,通过简单的二步方法成功合成了NiO亚微米球。第一步,以Ni(CH3COO)2和精氨酸为主要反应物,160℃溶剂热反应8 h制备出前驱体;第二步,煅烧前驱体成功合成了NiO产物。利用X射线粉末衍射(XRD),扫描电子显微镜(SEM),透射电子显微镜(TEM),热重分析(TGA)等手段对产物进行了表征。在紫外光照射下,研究不同光催化剂对甲基橙溶液降解效果。结果表明,NiO亚微米球在紫外光照射条件下对甲基橙溶液有光降解作用。

| Abstract: | NiO microspheres were synthesized by a two-step method with mixed solvent system.Firstly,NiO precursor were synthesized by a simple solvent-thermal method at 160 ℃ for 8 h using Ni(CH3COO)2 and L-arginine as reactants.Secondly,the precursor was calcined to obtain the product of crystalline NiO.The as-synthesized samples were characterized by X ray powder diffraction(XRD),scanning electron microscopy(SEM),transmission electron microscopy(TEM) and thermal analysis(TGA).The photocatalytic activity of the products was examined by measuring the photodegradation of methyl orange solution with ultraviolet radiation.The result showed the as-synthesized products had an excellent photocatalytic activity to photodegradation of methyl orange solution. |
