摘　　要：以硫酸镍(NiSO4·7H2O)为镍源,尿素为pH调节剂,采用表面活性剂辅助的水热法成功制备出了枝状Ni2P微晶。X-射线粉末衍射(XRD)、场发射扫描电子显微镜(FESEM)和紫外-可见分光光度计(UV-Vis)对所得产物进行表征。结果表明,所得产物为纯六方相的磷化镍(Ni2P),其形貌为有明显主干和高度有序分支的树枝状结构。其中,表面活性剂(SDBS)在枝状Ni2P微晶的整个生长过程中起到模板作用。对所得产品光催化性能研究发现,枝状Ni2P微晶能够很好地光催化降解亚甲基蓝溶液,降解率较高。Dendritic Ni2P microcrystalline were successfully synthesized via a surfactant-assisted hydrothermal route using NiSO4·7H2O as Ni source and urea as pH regulator. The as-obtained products were characterized by means of X-ray diffraction（XRD）,field-emission scanning electron microscopy（FE-SEM） and UV-Vis spectrophotometer（UV-Vis）. The results show that the products are pure Ni2P with hexagonal phase and have a dendritic morphology. The surfactant（SDBS） acts as a template in the dendritic growth process. The photocatalytic property of the product was investigated by the degradation of Methylene blue. The result show that the dendritic Ni2P microcrystalline exhibit good photocatalytic activities for methylene blue.
