摘要: 通过简单的液相法制得FeWO4微米晶,FeWO4微米晶于310℃、空气气氛条件下烧结,研究了烧结反应对FeWO4微米晶光催化性质的影响。烧结前后的样品通过X射线粉末衍射、扫描电子显微镜、透射电子显微镜、N2吸附-脱附、热重分析、红外分析和紫外-可见等分析方法加以表征。光催化实验证明烧结后其在降解罗丹明B溶液中表现出了较高活性,说明烧结反应有利于提高FeWO4的吸附与光催化性能。

Abstract: FeWO4 microcrystals were fabricated through a simple solution-based route. Then, FeWO4 samples were annealed under the circumstance of air, with the temperature of 310℃, and the annealing process is firstly studied for its influence on FeWO4 microcrystals. The FeWO4 microcrystals, before and after annealing treatment, were characterized by XRD, SEM, TEM, N2 adsorption-desorption, TG, IR, and UV-Vis analysis. Annealed FeWO4 samples show highly active in degradation of rhodamine B (RhB). It reveals that the adsorptive and photocatalytic properties of FeWO4 microcrystals are probably enhanced through annealing treatment.
