Construction Of Transition Metal Oxide Nanomaterials And Their Property And Application Research

Recently, considerable research interest is focused on transitional metal oxides nanomaterials. Due to the wide potential applications of transitional metal oxides nanomaterials, researchers did much many experiments to wish to control their nanostructure, composition and morphology. As a result, developing simple methods to fabricate various transitional metal oxides and researching their properties and uses are very interesting. At the same time, they are useful to extend the range of their applications in various fields.In the recent study, controlled preparation of transitional metal oxides can be achieved by selecting substrate, controlling nucleation and growth process and changing reaction environment. That requires us to develop new strategies, which are simple and low cost synthesis of transitional metal oxides materials.1. Porous Co₃O₄ nanorods with average diameter of 200 nm and length of 3–5μm was prepared via microemulsion-based method in combination with subsequent calcination process. The optical property of Co₃O₄ nanorods was investigated. Moreover, the porous Co₃O₄ nanorods exhibited high electrochemical performance when applied as the cathode materials for lithium-ion batteries, which gives them good potential applications cycle lifes.2. High quality superparamagnetic Fe₃O₄ nanoparticles of 200–300 nm were successfully synthesized through solvothermal method at 180 oC and prepared superparamagnetic mesoporous silica particles via CTAB as template. And realized the assembly of superparamagnetic mesoporous silica particles and polyelectrolyte, PAH and PSS.3. The anticancer chemotherapeutic agent PM–19 was loaded into the mesoporous channels to fabricate the pH/magnetic responsive drug controlled-release system.
