The porous α-Fe2O3 was used as solid support, and silver nanoparticles were integrating into the pore of α-Fe2O3 through hydrothermal synthesis. Four different amounts of AgNO3 were added into the growth media for optimizing the surface-enhanced Raman scattering (SERS) performance of Fe2O3-Ag. The structure and component of the Fe2O3-Ag nanocomposites were characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and N2 adsorption. The experimental results show that the BET surface area and enhancement factor of the Fe2O3-Ag nanocomposite are 26.57 m2/g and 102-103 respectively, when the dosage of AgNO3 is 6.5% (in mass), exhibiting the best SERS enhancement. The Fe2O3-Ag nanocomposite provides not only the SERS enhancement but also a good adsorption performance, which could be further used for absorption and detection of various samples.

以多孔α-Fe2O3作为固相载体,通过水热合成法在α-Fe2O3孔道内沉积银纳米粒子。测试4种不同硝酸银用量时Fe2O3-Ag复合物的表面增强Raman散射光谱性能(SERS)。利用扫描电子显微镜、透射电子显微镜、X射线衍射和N2吸附等表征手段对Fe2O3-Ag复合物结构及组成进行分析表征。结果表明,当银纳米粒子的负载量为6.5%时(质量分数),Fe2O3-Ag纳米复合物的比表面积为26.57 m2/g,增强因子可以达到102~103,SERS活性最好。所制备的Fe2O3-Ag纳米复合物具有良好的SERS活性和吸附性能,可以进一步应用于其他待测物的吸附检测。

以多孔α-Fe2O3作为固相载体,通过水热合成法在α-Fe2O3孔道内沉积银纳米粒子。测试4种不同硝酸银用量时Fe2O3-Ag复合物的表面增强Raman散射光谱性能(SERS)。利用扫描电子显微镜、透射电子显微镜、X射线衍射和N2吸附等表征手段对Fe2O3-Ag复合物结构及组成进行分析表征。结果表明,当银纳米粒子的负载量为6.5%时(质量分数),Fe2O3-Ag纳米复合物的比表面积为26.57 m2/g,增强因子可以达到102~103,SERS活性最好。所制备的Fe2O3-Ag纳米复合物具有良好的SERS活性和吸附性能,可以进一步应用于其他待测物的吸附检测。

The porous α-Fe2O3 was used as solid support, and silver nanoparticles were integrating into the pore of α-Fe2O3 through hydrothermal synthesis. Four different amounts of AgNO3 were added into the growth media for optimizing the surface-enhanced Raman scattering (SERS) performance of Fe2O3-Ag. The structure and component of the Fe2O3-Ag nanocomposites were characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and N2 adsorption. The experimental results show that the BET surface area and enhancement factor of the Fe2O3-Ag nanocomposite are 26.57 m2/g and 102-103 respectively, when the dosage of AgNO3 is 6.5% (in mass), exhibiting the best SERS enhancement. The Fe2O3-Ag nanocomposite provides not only the SERS enhancement but also a good adsorption performance, which could be further used for absorption and detection of various samples.
