以胶原纤维为模板,首先将Zr(Ⅳ)负载在胶原纤维上,然后吸附磷,最后经高温煅烧除去胶原纤维模板制备了介孔磷酸锆钠(NaZr2(PO4)3,NZP)。利用电感耦合等离子发散光谱仪(ICP)、X射线衍射仪(XRD)、场发射透射电镜(FETEM)、X射线光电子能谱(XPS)、傅立叶变换红外光谱(FT-IR)、N2吸附/脱附分析等对NZP进行了表征。结果表明,胶原纤维模板在800℃时即可完全去除,并形成介孔结构;当以磷酸二氢纳(NaH2PO4)为磷源、n(Zr)/n(P)=0.62时,经800℃煅烧得到了介孔率为97%的NZP。
The mesoporous NaZr2 (PO4)3 (NZP) is prepared using collagen fiber as template. The Zr( Ⅳ ) is first loaded on collagen fiber and then the phosphate is adsorbed. This precursor is heat treated and the mesoporous NZP is obtained. Inductive coupled plasma emission spectrometer (ICP), X-ray diffraction(XRD), field emission transmission electron microscope(FETEM), X-ray photoelectron spectroscopy(XPS), fourier transform infrared spectrometer(FT-R) and N2 adsorption/desorption techniques are used to characterize synthesized mesoporous NZP. The experimental results indicate that the collagen fiber template can be completely removed at 800℃, as a consequence the NZP with mesoporous structure is obtained. It is found that the mesopore extent of NZP is 97% using Nail2 PO4 as phosphate source and n(Zr)/n(P)=0. 62.
