采用微波辅助加热法,以ZrOCl_2、NH_4F、CuCl_2及NaH_2PO_4为原料,水为溶剂,一步法制备磷酸锆铜(CuZr(PO_4)_2 · 4H_2O).运用X射线衍射(XRD)、扫描电子显微镜(SEM)、场发射扫描电子显微镜(FE-SEM)、能谱仪(EDS)、电感耦合等离子体原子发射光谱(ICP-AES)、紫外-可见漫反射光谱(UV-Vis DRS)和比表面积及孔隙分析仪(BET)等对产物的微结构、元素组成、比表面积和光学性能等进行了表征,同时考察了不同的合成条件对磷酸锆铜微观结构与形貌的影响.结果表明,当[Zr~(4+)]=0.005 mol/L,n(Cu)/n(Zr) = 1, n(F)/n(Zr) =6, n(P)/n(Zr) = 20, pH值为4.8时,在90 ℃条件下反应30 min,可得到尺寸均一、由纳米片插...

Copper zirconium phosphate （CuZr （PO4）2 ~ 4H20） was synthesized by microwave-assisted method using ZrOCI2, NH4F, CuC12 and NaH2PO4 as raw materials and water as solvent. The microstructure, elemental composition, specific surface area and optical property of copper zirconium phosphate were characterized by XRD （X-ray diffraction）, SEM （scanning electronic microscopy）, FE- SEM（field emission scanning electron microscopy）, EDS （energy dispersive spectrometer）, ICP-AES （inductively coupled plasma-atomic emission spectrometry）, UV-Vis...
