In this paper, our aim was to develop the Neodymium oxide (Nd2O3) based nano composites using sol gel method. This work is mainly focused on to study the synthesis of metal composites by sol gel method. We will also observe the morphologies and dimension of neodymium oxide doped nano composites are influenced due to alteration in growth parameters such as different composition or thermal treatment. The structure of the sample prepared was studied using optical microscope. The other objective would be to investigate the synthesis of modem oxide doped nano composites.

Metal oxide nano-composites plays a very important role in many areas of chemistry, physics and material science. This paper explains the synthesis and comparison of zinc and zirconium doped TiO2 metal oxide nano-composites and their different properties. Here the sol-gel method is used to synthesis both the nano-composites. Nano-composites have been characterized with XRD, AFM, Zetasizer & potential and FT-IR studies. XRD study revealed good crystallinity with the size range of 30 nm – 45 nm for both nano-composites. AFM studies also revealed the same. FTIR study reports the characteristics peaks of synthesised nano-composites.

Abstract In the present study, Fex/ZrO2 (0 ≤ x ≤ 25) nanoparticles were synthesized by a facile modified Sol-Gel method. Stabilization of the tetragonal phase of ZrO2 is studied as a function of both the Fe incorporation ratios and thermal treatment. The Fe incorporation ratios are tested up to the extreme just before FeO and Fe2O3 phases are formed separately. The prepared Fex/ZrO2 nanoparticles XRD analysis depicts the formation of zirconium oxide at different Fe ratios in the nanoscale with an excellent degree of crystallinity in the tetragonal phase. The effect of thermal treatment on stabilizing the tetragonal phase of Fex/ZrO2 nanoparticles is extensively studied. The phase transition to the monoclinic phase is determined as function of Fe incorporation ratios and annealing temperatures. The optical absorbance spectra showed that the optical band gap decreased with increasing Fe ratios without the formation of doping bands which confirms the formation of Fex/ZrO2 single matrix.

Titanium Tetra Isopropoxide

The aims of this study are to analyze the effect of acidity and rotational speed in the synthesis of TiO2 using the sol-gel method and to analyze the morphology of synthesized TiO2 nanoparticles and commercial TiO2 using XRD to produce semiconductors for Dye-Sensitized Solar Cell (DSSC) applications. The sol-gel method was used to synthesize TiO2 Nanoparticles. Titanium tetra-isopropoxide (TTIP) was used as a precursor with the variable of the magnetic stirrer rotation speed of 500, 1000 and 1500 rpm. Acidification was achieved by adding acetic acid to Sol-gel solution to produce a pH number of 1, 2, and 3. Nanomaterial was observed with an optical microscope and X-ray Powder Diffraction (X-RD) to determine the morphology and phase of TiO2 crystalline. The results showed that the rotational speed and acidity level of the Sol-gel solution ware played an important role to get the best form of a nanoparticle. At a rotation speed of 1500 rpm with pH 3 and 1000 rpm with pH 2 ware shown characteristics similar to commercial TiO2. In addition to that, the results of XRD characterization of synthesized TiO2 was shown a crystal phase of anatase structure with 18,046 nm crystal size compared to commercial TiO2 with anatase structure and crystal size of 15,554 nm.
