【摘要】 采用了一种全新的表面活性剂——酵母．以硝酸锌为原料,氨水和尿素为沉淀剂,运用仿生法与均匀沉淀法相结合制取纳米氧化锌,并利用多种测试手段进行性能表征．试验结果表明,制得的氧化锌颗粒较小, 加入酵母后,氧化锌的性能有了显著提高,烧结温度在 300和600℃时的氧化锌具有很好的光催化性．更多还原

【Abstract】 The yeast is used as a new kind of surfactant in this paper.Using zinc nitrate as the starting material and ammonia and urea as precipitating agent,we prepared nano-ZnO powder by bionic method and homogeneous precipitation method.By various experiment analysis we can know that ZnO have a better performance and smaller size when we use yeast as a surfactant.ZnO also have good light catalyst when the temperature is at 300 and 600℃.更多还原
