摘　　要：基于脱脂棉为牺牲模板,采用碳辅助法制备了内嵌碳的八面体形貌Co3O4,对其在模拟阳光下的光解水制氢气的能力进行了研究。X射线衍射(XRD)和扫描电镜(SEM)表征分析表明,制备的产物是具有规则正八面体形貌、粒径约为10μm的具有良好晶型的Co3O4。能谱(EDS)和光射线光电子能谱(XPS)结果表明,制备的产物内嵌无定形碳,碳源来自于脱脂棉制备过程中的不完全燃烧。实验结果表明制备的内嵌碳八面体形貌Co3O4具有良好的光解水制氢能力。Carbon-incorporated octahedral Co3O4 was synthesized via a novel and environment-friendly one-pot method using degreasing cotton as the sacrificial templates and its photocatalytic ability on producing H2 from water/ethanol solution under simulated solar light condition was investigated.X-ray diffraction(XRD)and scanning electron microscope(SEM)were performed to characterize the structure and morphology of the octahedral Co3O4 with a particle size of about 10 um.The energy dispersive spectrometer(EDS)manifested the incorporation of carbon species into octahedral Co3O4 and the X-ray photoelectron spectroscopy(XPS)confirmed that the carbon species come from the incomplete combustion of the degreasing cotton.The probable formation procedure of the carbon-incorporated octahedral Co3O4 was proposed.Notably,the resultant Co3O4 exhibited a promising capability on splitting water into H2.
