|
Abstract:
在本文中，通过一步溶剂热的方法合成了直径约为240 nm的Fe3O4@C纳米球。利用SEM、Mapping、XPS、ESR对产物的形貌、结构和表面特征进行了详细的表征。在室温条件下，Fe3O4@C纳米球的饱和磁化强度为72 emu g？1。此外，在过氧化氢溶液中，所合成的Fe3O4@C纳米球显示出优异的催化降解染料污染物的活性。
In this study, Fe3O4@Cnanospheres with a diameter of about 240 nm was synthesized by one-pot solvothermal method. The morphology, structure, and surface characteristics have been studied through SEM, Mapping, XPS, and ESR. The saturation magnetization of Fe3O4@Cnanospheres was about at room temperature. Moreover, the assynthesized Fe3O4@Cnanospheres showed excellent catalytic activity for degradation of dye pollutants in H2O2 solution.
