Abstract

Nanosized fibrous cerium phosphate, Ce(HPO₄)₂.2.9H₂O(nCeP_f), and α- Zirconium -Titanium Phosphates, Zr_xTi_1-x(HPO₄)₂.H₂O(α-ZTP), where x = 0.9, 0.8, 0. 67, 0.34, were synthesized. Novel composite membranes [Zr_xTi_(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: [(H_1.16) Zr_0.9Ti_0.1 (PO₄)₂]_0.25[(H_1.16 ) Ce (PO₄)₂]_0.75(PhenCu)_0.42.2.25H₂O, [(H_1.5)Zr_0.8Ti_0.2 (PO₄)₂]_0.25 [( H_1.5)Ce (PO₄)₂] _0.75 (Phen Cu)_0.25.1.77H₂O, [(H_0.3 ) Zr_0.67Ti (PO₄)₂] _0.25 [(H _0.3) Ce (PO₄)₂]_0.75.(Phen Cu)_0.85. 4H₂O, [(H_1.6)Zr_0.34Ti_0.66 (PO₄)₂]_0.25 [(H_1.6) 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 nCeP_f, 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.
