以脱脂棉和氯化钴为原料，采用碳辅助一步法合成了八面体Co3O4(∼1μm)。表征结果表明，前驱体的焙烧温度、焙烧时间、反应前驱体、氧气环境以及前驱体的反应物比对Co3O4粉末的制备有重要影响。UV-Vis光谱的结果还表明，得到的八面体Co3O4可以用于可见光照射下的光催化分解水。
Octahedral Co3O4 (∼1 μm) was synthesised by a one-step carbon-assisted method using degreasing cotton and cobalt chloride as precursors. The characterisation results show that the calcination temperature, calcination time, reaction precursor, oxygen environment and reactants ratio of the precursor play important roles in fabricating the Co3O4 powders. The result of the UV-vis spectrum also shows that the octahedral Co3O4 obtained can be applied in photocatalytic water splitting under visible light irradiation.
