鉬酸銅的制備及其表征


摘要
本論文主要是使用水熱法制備空心球狀堿式鉬酸銅顆粒。該制備過(guò)程受溫度、反應(yīng)時(shí)間、尿素的量、以及表面活性劑的強(qiáng)烈影響。以控制單一變量為原則，在恒定的反應(yīng)時(shí)間內(nèi)，分別改變尿素的量、表面活性劑、溫度等影響因子，研究其對(duì)微觀形貌的變化。通過(guò)XRD與掃描電子顯微鏡對(duì)其成分、形貌進(jìn)行表征后得知：易于在120℃、加熱12h、加1mmol尿素、不加表面活性劑條件下選擇性控制合成鉬酸銅納米球。并采用微乳液法在120 ℃、加熱12 h、加尿素、pvp表面活性劑制備堿式鉬酸銅微米球。結(jié)果表明水熱法和微乳液法是選擇性合成大量堿式鉬酸銅微米球/微米片的簡(jiǎn)單方法。

Preparation and Characterization of Copper Molybdate
Abstract

This thesis is to apply the Hydrothermal Synthesis to produce and prepare hollow spherical molybdate copper nanoparticles. The process is strongly influenced by the temperature, reaction time, the amount of urea, and the surface active agent. In accordance with the principle of controlling the single variable, it changes, respectively the amount of urea, surfactant, temperature and other affecting factors, studying its changes on microscopic morphology. After demonstrating its composition and morphology by XRD and scanning electron microscopy, this thesis finds that: it is apt to synthesize molybdate copper nanospheres in the condition of 120 ° C, heating 12h, adding 1mmol urea, and no surfactant conditions. It then applies microemulsion method in the condition of 120 ℃, heating 12h, plus urea, pvp surfactant to produce and prepare molybdate copper nanospheres. The results show that the hydrothermal method and microemulsion method are two simple methods to synthesize selectively a large number of molybdate copper nanoparticles / micron chip.
