Abstract

Pellicular -zirconium phosphate-phosphite and nanofibrous cerium phosphate, -Zr.PO4.H2PO3.2H2O (p-ZrPP), Ce(HPO4)2.2.9H2O(nCePf ), respectively, were prepared and characterized by chemical, X-ray, thermal analysis and by FT- IR spectra. Composites of pellicuarl -zirconium phosphate-phosphite/nanofibrous cerium phosphate membranes were prepared by mixing slurry aqueous solutions of (p-ZrPP ) and (nCePf) at 450C for 48h, where the mixing ratios were 33:67 and 25:75 wt/wt%, p-ZrPP:nCePf, respectively. The resultant composite materials found to be:
[-Zr.PO4.H2PO3]0.34[Ce(HPO4)2]0.66.2.86H2O,and[-Zr.PO4.H2PO3]0.27[Ce(HPO4)2]0.73.2.17H2O, respectively. The composite membranes were homogeneous, flexible thin films with good mechanical texture. The resultant composites were
characterized by chemical, x-ray, thermal analysis and by FT- IR spectra. Tailor made of pellicular -Zirconium phosphate- phosphite /nanofibrous cerium phosphate composite membranes can be obtained , which mainly depend on wt/wt% mixing ratios of (p-ZrPP) /(nCePf) .These composites can be considered as new ion-exchangers , ionic conductors, and as solid acid catalysts.
