Synthesis And Applying Research Of Nano-Oxide And Its Composite Nanostructure

Due to their superior properties on optics,electricity,mechanics,physics and chemistry,the research of nanomaterials has become increasingly important with the development of science and technology,which includes basic study on physics,chemistry,biology and the synthesizing and application of Micro/Nanostructures.New technique and technology lead to new findings on the study of nano oxide and its composite structure.The fabrication and application of wide-band metal oxide nanostructure such as ZnO is one of the focuses of current nanomaterials studies.ZnO nanomaterials are good semiconductor Functional Material that have all the potential features of nanomaterials.This paper mainly expatiates the synthesizing of several shapes of ZnO nanostructures of ZnO monocrystal through hydro-thermal method and thermal vapor method,and studies the mechanism of self-organizing growing nano-structure and field emission performance of ZnO nano-structure.Also studies the process of decomposing CH₄ to get carbon nanotube MWNT using La₂Ni0₄ as catalyzer,the synthesizing of nano-composite structure from ZnO nanomaterials and MWNT,based on MWNT paste substrate with thermal vapor method,and the performance of photoluminescence and glucose sensors.As an environmental friendly Semiconductor Functional Materials,Cu₂O is widely used in multifunctional material in catalysts,gas sensors,electronics,lithium ion batteries,and solar energy conversion.This paper investigates the synthesizing of Cu₂O film from quartz,and analyzis its dielectric function,electronic band,and electrical transition properties by Raman scattering,PL,and temperature dependent transmittance measurement.then comes up with IV Dielectric function theory model to fit the experimental data of transmittance measurement,and elaborates the influence that temperature contributes to electronic band structures at last.Ti0₂ holds good electron property and catalytic performance and 3D TiO₂ nano-structure has the advantages of high degree of crystallinity and specific surface area,that will contribute more Hydrogen evolution active sites.Its specific hydrophilic property will also do good to increase the materials' hydrogen-evolution activities,so it has a mature application in the field of Hydrogen evolution.As a typical transition metal sulfide,MoS₂ is low in price and has good chemical stability and Hydrogen evolution.In this paper,Synthesizing of MoS₂ and TiO₂ powder through hydro-thermal method are studied,the means of getting the different heterojunctions and bidirectional composite of MoS₂ and Ti0₂ are also discussed by controlling these two materials' growing sequence to increase their Hydrogen evolution active site for Hydrogen Reaction efficiency.
