p-n型CuO/α-Fe2O3复合半导体材料的制备与气敏性能研究
Synthesis and Gas Sensing Properties of p-n Type CuO/α-Fe2O3 Nanomaterials
摘要
Abstract
CuO and α-Fe2O3 nanomaterials were prepared by the chemical precipitation method.And,the pn type semiconductor metal oxide composite was successfully prepared by the deposition-precipitation method.The structure and morphology of the as-prepared samples were characterized by the techniques of powder X-ray diffraction (XRD),scanning electron microscope (SEM),transmission electron microscopy (TEM) and Xray photoelectron spectroscopy (XPS).The analysis results indicated that when the content of CuO was small,the CuO nanoparticles were high dispersed on the surface of α-Fe2O3.When the content of CuO over 30mol％,the new phase of CuFe2O4 was formed.The SEM and TEM images showed that the obtained sample consisted of the nanoparticles with the size of about 10 nm.关键词
