1、磁性金納米星論文：核殼結(jié)構(gòu)磁性納米復(fù)合粒子的制備及其催化性能的研究【中文摘要】超順磁性Fe3O4納米粒子（NPs）由于具有粒徑小、靈敏度高、毒性低、磁響應(yīng)性強(qiáng)、原料易得到等優(yōu)點(diǎn)，被選為最佳的磁性材料。同時(shí)由于其在磁共振成像、磁力引導(dǎo)藥物輸送、熱療法以及磁分離方面的應(yīng)用潛力，使以超順磁性Fe3O4NPs為起始原料合成具有核殼結(jié)構(gòu)的納米晶體一直成為人們研究的焦點(diǎn)。本文提出一種室溫條件下，采用晶種生長法在水相中合成磁性金納米星的簡易方法，該方法合成的納米星不僅具有磁性，還在紫外可見光區(qū)還具有可調(diào)控的光學(xué)性質(zhì)。同時(shí)，我們制備的磁性金納米星對(duì)硼氫化鈉【英文摘要】Manyat
