摘要

以CuSO₄·5H₂O为铜源,Na₂WO₄为钨源,通过改变多种水热反应条件制备出了CuWO₄粉体,利用X射线衍射分析 (XRD)、扫描电子显微镜 (SEM)等分析手段对样品的形貌结构进行了研究,并以罗丹明B作为降解物、可见光作为光源,对产品的光催化性能进行了评价。结果表明,制备CuWO₄纳米粉体材料的适宜条件:pH=4,反应温度为180℃,反应时间为12h,铜钨浓度比Cu²⁺∶WO^2-₄=1∶1,产物降解效率可达97.1%。

Abstract

CuWO₄ nanoparticles were prepared by changing various hydrothermal reaction conditions with CuSO₄·5H₂O as copper source and Na₂WO₄ as tungsten source.the morphology and structure of the sample were studied by x-ray diffraction analysis (XRD) and scanning electron microscopy analysis (SEM).the photocatalytic performance of the product was evaluated with rhodamine b as degradation product and visible light as light source.The results showed that the suitable conditions for preparing CuWO₄ nanoparticle material were pH=4,reaction temperature T=180℃,reaction time t=12 h,copper-tungsten concentration ratio Cu²⁺∶WO^2-₄=1∶1,and the degradation efficiency of the product reached 97.1%.
