由于从茶叶中提取的多羟基酚性物质茶多酚具有活性羟基多、无毒无害、对金属离子沉淀率高的优点 ,因此利用茶多酚作为有机沉淀剂制备了氧化锌纳米微粉 ,研究了前驱体的形成条件、分解温度、焙烧时间 ,并对所得纳米颗粒进行了表征 Since polyphenols polyphenols extracted from tea have the advantages of active hydroxyl groups, innocuity and harmlessness, and high precipitation rate of metal ions, zinc oxide nano-micron powder is prepared by using tea polyphenol as organic precipitant. Precursor formation conditions, decomposition temperature, calcination time, and the resulting nanoparticles were characterized
