鉭酸銅的制備及其表征

摘要
納米粒子的調(diào)控合成是納米科技發(fā)展的重要的組成部分，是探索納米結(jié)構(gòu)性能及應(yīng)用的基礎(chǔ)。本論文主要通過(guò)水熱法和共沉淀法合成鉭酸銅，并對(duì)合成的產(chǎn)物進(jìn)行多種方法的表征。通過(guò)改變水熱法的合成體系的實(shí)驗(yàn)條件如：保溫溫度，保溫時(shí)間，添加不同的添加物等，進(jìn)行一系列的對(duì)比試驗(yàn)；改變共沉淀法過(guò)程中的滴加物如：氫氧化鈉，氨水等，進(jìn)行對(duì)比實(shí)驗(yàn)。然后將各組實(shí)驗(yàn)所得的樣品進(jìn)行掃描電子顯微鏡檢測(cè)和XRD物相定性分析檢測(cè)，從而對(duì)比分析得出在實(shí)驗(yàn)室中制備鉭酸銅的最佳方法和條件。

The preparation and characterization of copper tantalate
Abstract
Regulation of the synthesis of the nanoparticles is an important part of the development of nanotechnology, for exploring the basis of the performance and applications of nanostructures. In this thesis,copper tantalate was prepared by hydrothermal synthesis and coprecipitation synthesis, and products were characterized by a variety of methods . We conducted a series of comparative tests by changing the experimental conditions such as holding temperature , holding time, and different additives in the hydrothermal synthesis system. Then the samples were characterized by SEM and XRD, and finally through comparison and analysis we obtained the best methods and conditions of preparing tantalate copper tantalate nanocrystalline in the laboratory.
Keywords: copper tantalate; hydrothermal synthesis; coprecipitation synthesis; nanomaterial
