| 摘 要： | 氧化镁是一种具有重要工业用途的物质,在催化、陶瓷、塑料和橡胶等领域有着广泛的应用.当尺寸细化至纳米量级后,因纳米材料所特有的体积效应和表面效应,纳米氧化镁在低温烧结、微波吸收、催化性能等众多方面呈现出许多不同于本体材料的热、光、电、力学和化学特性,因而引起了人们广泛的研究兴趣[1,2].其中氧化镁纳米线、纳米带、纳米管等一维纳米结构材料以其新颖的结构形式及与之相关的性能,近年来更为引人关注.

| Abstract: | MgO nanobelts were successfully synthesized via a co-precipitation synthetic way by employing ammonia and salvolatile as co-precipitator. TEM characterization showed that these nanobelts were composed of uniform hexagonal shaped MgO nanocrystals. The formation of this new-type nanostructures was attributed to the crystal structures of the MgCO3·3H2O precursor. TG was adopted to show the gradual conversion process of from MgCO3·3H2O to MgO. Due to the large surface areas and the largely exposed (100) surfaces, these nanobelts may find their applications in catalysis fields. |
