A. CARAMBOLA FRUIT JUICE AS A PRECIPITATING AGENT IN A MODIFIED OXALATE SYNTHESIS ROUTE TO NANOSTRUCTURED SINGLE AND HETERO OXIDES
Abstract
In this work, single molecular precursors of Zn, Ti-doped Zn, Cu, Ti, Ti/Cu system, and the multiple metal (Ca, Cu, Ti) system were synthesized via a modified oxalate route by co-precipitation using A.carambola fruit juice and commercial oxalic acid as the precipitating agents. The single molecular precursors generated were characterized by FT-IR, TGA/DTG and XRD.
The FT-IR results confirmed the presence of the carboxylate group in both the commercial oxalic acid and carambola fruit juice. The TGA/DTG results revealed that the precursors decomposed at temperatures in the range 450-700 oC: 450 ∘C for pure copper and zinc oxalates; 600 ∘C for the as-prepared precursors containing titanium ions; and 700 oC for the multiple metal (CCTOX = Ca, Cu, Ti oxalate) system.
On the other hand, the EDS and XRD results confirmed the metallic contents in the precursors and showed that the metal-ligand bonding is via the carboxylate group of the oxalate ion in both the carambola fruit juice and the commercial oxalic acid.
The precursors thus obtained were Zn C2O4, Ti-doped Zn C2O4, CuC2O4, TiO2(OH−)2C2O4, copper-doped titanium hydroxyl oxalate, copper titanium hydroxyl oxalate, and calcium copper titanyl oxalate.
The precursors were then thermally decomposed in a muffle oven at temperatures between 450-700 oC according to the optimal decomposed temperatures predetermined by TGA/DTG analysis as specified above.
The decomposition products were characterized via XRD, SEM/EDAX and VSM. The XRD results from the decomposition product revealed the decomposition, products to correspond to ZnO, Ti-ZnO, CuO, TiO2, Cu0.131Ti0.869O2, CuO/TiO2 and Ca2Cu3TiO12.
In addition, calculations based on XRD results and SEM micrographs indicated that the powder samples generated were nanostructured (nano-sized).
The SEM results also revealed that the nanopowdered material were homogeneous and showed very little agglomeration. The elemental analysis from EDAX revealed that the metal contents of the powders produced matched those of the precursor substances.
Finally, VSM results revealed that the nanostructure Ti-doped ZnO generated from this work is a ferromagnetic material.
These results demonstrate that the modified oxalate technique making use of A. carambola juice as precipitating agent is simple, renewable, environmentally friendly, of low cost, is controllable and can also be applied to the preparation of a wide variety of mixed metal oxides of interest.
The resulting oxides can also serve as ceramic materials for harnessing and storing energy in solar cells – a renewable source of energy.
