Book excerpt: \Alpha$-Fe_2O_3$ nanoparticles and Silica Coated $Fe_2O_3$ Particles were synthesized by hydrothermal method and acid - base hydrolysis of TEOS respectively. The Core Shell Particles has been characterized by SEM, XRD, and Particle size analysis. From particle size analysis, it was seen that, the distribution maxima of $Fe_2O_3$ and $Fe_2O_3@SiO_2$ coated nanoparticle were of 120 & 350 nm, 150nm & 550 nm respectively. From XRD analysis, it was confirmed that silica sample nanoparticles is amorphous in nature. The SEM/EDX analysis data represents the presence of $Fe_2O_3@SiO_2$ and show only the compositions of $Si, O & Fe2O_3$ peaks. As $Fe_2O_3$ nanoparticles show applications in many fields including high density magnetic storage devices, ferrofluids, magnetic refrigeration systems, and catalysis. Aggregation of nanoparticles can be prevented by coating the particles with other materials. The core/shell structure enhances the thermal and chemical stability of the nanoparticles, improves solubility, makes them less cytotoxic and allows conjugation of other molecules to these particles.

This book was released on 2000-02-21 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Materials with nanometer size particles exhibit unique chemical and physical properties. In particular, nanocomposite materials, composed of nanometric metal and metal oxide particles embedded in vitreous matrices, present a variety of interesting magnetic, electric and catalytic properties, that are strongly size-dependent. Among the different preparation methods which can be used to obtain this kind of materials, the sol-gel process is particularly interesting because it is affected by several parameters which allow a versatile control of the structural, textural and chemical properties of the final products. The present volume focusses on the preparation of metal-silica and metal oxide-silica (Me=Ni, Fe, Zn) nanocomposites by the sol-gel method and the characterization of their structural and magnetic properties.

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis reported synthesis of TiO2 nanostructures and Fe2O3 nanostructures and studied on self-assembling process. The morphologies, compositions, and physicochemical properties of the prepared samples were characterized by TEM, FESEM, XRD, FTIR, UV, and SQUID etc. Nanoparticles of transition metal oxides own their special function to become an interesting hot research topic in the recent decades. In particular, superparamagnetic iron oxide nanoparticles can be used as drug delivery agent and new hard disc drive materials. They have wide application in environment industry as well. Titanium dioxide nanoparticles can be applied in photocatalysts, UV protectors and dye sensitive solar cell etc. Their wide industrial applications for advanced technology development motivate scientists to develop simple, economical and novel synthetic methods, and explore their applications, so that the commercialization of the production of the nanomaterials becomes feasible. The objective of this project is to develop an effective, simple and economical technical route for synthesis of nanosized iron oxide and titanium oxide particles/rods/films. The approach and the progress are outlined as follows. Based on extensive literature reading on the project related area, a novel self-assembling technical route for iron oxide nanostructure and architecture was proposed which has been confirmed to be effective. Detailed experimental investigation on the synthesis of nanoparticles/rods, and instrumental characterization of the particle size, structure, and crystallites, etc. via TEM, FESEM, XRD, FTIR, UV, SQUID are conducted. Uniform nanorods of hematite iron oxide and titanium oxide nanospheres, and anatase TiO2 thin film with micropores have been successfully achieved. Some preliminary exploration for applications of the synthesized nanomaterials has also been carried out. Firstly, a novel assembled scheme of iron oxide nanostructure and architecture by selfassembling process was investigated. The sol-gel technical route was employed to synthesize nearly uniform nanorods of hematite particles. Morphologies and physicochemical properties of iron oxide nanostructure were characterized by analytical instrument. Secondly, titanium oxide nanospheres were synthesized via a hydrothermal process using titanium isopropoxide as the precursor. Titanium oxide nanospheres with inner nanospace andhighly organized crystallites in the shell structure and surface regions were synthesized. It demonstrated that the technical route developed in this work has a high versatility for structural engineering of various targeted morphological products. Thirdly, a simple process of preparing anatase TiO2 thin film with micropores was pursued. The synthesized nano thin film with micropores was used for the material of dye-sensitive solar cell; and effective electron transfer of titanium oxide electrode was confirmed by electrochemical voltammetry. Preparation of the titanium oxide electrode and its electrochemical analysis was studied. The application of the titanium oxide of microporous thin film material as a promoter for electrochemistry voltammetry measuring system was explored in this thesis. In conclusion, the iron oxide nanorods with superparamagnetic property were successfully synthesized by a simple method with low cost materials. Titanium oxide hollow nanospheres were achieved by the assistance of copolymer template. Titanium oxide thin film with microporous structure with significantly high efficiency in electron transfer was realized. Further researches on the synthesis of hybrid iron oxide and titanium oxide nanoparticles, their crystal growth architecture and mechanism, as well as exploration of their applications are recommended.

This book was released on 2014 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: The composite material system of Iron (III) Oxide (Fe2 O 3 ) and Silica (SiO2 ) was explored due to the unique magnetic properties of Iron (III) Oxide along with the optical properties of Silica. Through a highly controllable and tunable chemical synthesis method utilizing reverse-micelle/sol-gel processes, phase and morphology of Iron (III) Oxide nanoparticles was controlled through variation of calcination temperature from 800oC - 1100oC. Four polymorphs of Iron (III) Oxide were observed. Furthermore, core-shell structures comprised of iron oxide cores and silica shells were created with relatively high initial iron oxide concentrations, and densified via Current Activated Pressure Assisted Densification (CAPAD). The densified core-shell were highly transparent despite mismatches in index of refraction of iron oxide and silica, and high initial concentrations of iron oxide.
