摘要:
以亲水性较强的多糖（蔗糖、纤维素等）为碳源，钴的硝酸盐为金属源，通过500 ℃碳化，700~1 000 ℃退火，浓硝酸浸泡纯化等工艺制备了碳包覆金属钴纳米颗粒.采用XRD、HRTEM等测试手段对产物的形态、组成和结构进行了表征，结果表明产物具有明显的Co/C核壳结构，金属Co核尺度为20~50 nm，碳壳一般由十到二十几个石墨结构层组成.此外，还系统考察了制备过程主要工艺参数参数，如碳源与金属初始比例、退火温度、退火时间等对碳包覆Co纳米颗粒形成的影响.
Abstract:
This paper used soluble polysaccharides （cellulose，sucrose，etc.） as substrate，cobalt nitrate as source for the metal，through 500 ℃carbonation and 700~1000 ℃ heat to systhesize and characterize carboncoated metal nanoparticles. By using XRD，HRTEM and other means to study the shape，composition and structure of the particles， the results showed that graphitic carboncoated cobalt nanoparticles have a perfect structure，with cobalt core / graphite shell，graphite coating layer in a dozen or so，and particles size between 20~50 nm. And the authors systematically inspected the preparation process and parameters，such as the amount of metal distribution，annealing temperatures and annealing time processing conditions on carboncoated cobalt nanoparticles forming impact.
