Abstract: Nanosized fibrous cerium phosphate, Ce(HPO4)2.2.9H2O(nCePf), and α- Zirconium -Titanium Phosphates, ZrxTi1-x(HPO4)2.H2O(α-ZTP), where x = 0.9, 0.8, 0. 67, 0.34, were synthesized. Novel composite membranes [ZrxTi(1-x)(HPO4)2]0.25 [Ce(HPO4)2]0.75 .3.3H2O were prepared. Reactions of the resulting composite membranes with 1,10-phenanthroline in ethanol, followed by the addition of 0.1M CuCl2.2H2O, in (1:1) ethanol: aqueous solution, lead to the formation of novel pillared materials: [(H1.16) Zr0.9Ti0.1 (PO4)2]0.25[(H1.16 ) Ce (PO4)2]0.75(PhenCu)0.42.2.25H2O, [(H1.5)Zr0.8Ti0.2 (PO4)2]0.25 [( H1.5)Ce (PO4)2] 0.75 (Phen Cu)0.25.1.77H2O, [(H0.3 ) Zr0.67Ti (PO4)2] 0.25 [(H 0.3) Ce (PO4)2]0.75.(Phen Cu)0.85. 4H2O, [(H1.6)Zr0.34Ti0.66 (PO4)2]0.25 [(H1.6) Ce (PO4)2]0.75.(PhenCu)0.2. 2.22 H2O, respectively. They were characterized by chemical, X-ray diffraction (XRD) and thermal analysis (TGA), accordingly were formulated. XRD patterns of the composite materials retain (d) spacing reflection of α-ZTP and nCePf, where d001 = 7.58 Å and 11.38 Å, respectively, The resulting composites are thermally stable and can be considered as novel ecofriendly solid acid catalysts, Ionex changers and ionc conductance materials.
