g-C3N4/Bi2S3复合材料的离子热法制备与表征

Preparation and Characterization of g-C3N4/Bi2S3 Composites by an Ionothermal Method

  • 摘要: 以离子液体为反应介质,Bi(NO33为铋源,硫脲为硫源,g-C3N4为载体,采用离子热法在不同反应温度下合成了g-C3N4/Bi2S3复合材料。采用XRD、SEM、紫外-可见光光谱和荧光光谱对所制备的g-C3N4/Bi2S3复合材料进行了表征。XRD结果显示,所制备的样品只有Bi2S3和g-C3N4物相;SEM结果表明,g-C3N4/Bi2S3复合材料中的Bi2S3呈纳米棒状;紫外-可见光谱结果表明,所制备的g-C3N4/Bi2S3复合材料在整个可见光范围有较强的吸收,尤其是当反应温度超过160℃所制备的样品在整个可见光范围光吸收值超过0.5;荧光光谱结果表明,随着反应温度的升高,所制备的复合材料荧光强度出现明显的衰减现象;同时对所制备的样品进行了热导率测试,结果显示,反应温度越高复合材料的热导率越大。

     

    Abstract: Bismuth sulphide (Bi2S3)/g-C3N4 composites were synthesized by an ionothermal method under defferent reaction temperature using Bi(NO3)3 as the bismuth source, thiourea as a sulphur source, and g-C3N4 as carrier in an ionic liquids reaction medium. The prepared samples were characterized by XRD, SEM, UV-vis spectrum and PL spectrum respectively. XRD results indicated that the prepared samples were only Bi2S3 phase and g-C3N4 phase in the Bi2S3/g-C3N4 composites. SEM results indicated that the Bi2S3 grains are nanorods. The UV-vis spectrum result indicated that the prepared samples exhibited stronger absorption over the entire visible light range. Especially when the reaction temperature was beyond 160℃, absorbance values of the prepared samples were beyond 0.5 over the entire visible light range. The PL spectrum result indicated that the fluorescence intensity of the prepared composites was obviously weakened with reaction temperature increasing. At the same time, the thermal conductivity of the prepared samples was tested. The result indicated that the thermal conductivity of the Bi2S3/g-C3N4 composites was increased with reaction temperature increasing.
