摘要/Abstract

摘要： 采用元素分析和红外光谱对所制磷钨酸1,3-二乙酸咪唑盐催化剂进行表征，考察了光照时间、催化剂用量对光催化降解有机染料甲基红效率的影响. 结果表明，无光催化剂时甲基红可直接光解，完全光解所需时间为220 min；催化剂用量为0.02?0.10 g时，对甲基红光降解效率随催化剂用量增加显著提高；加入0.08 g催化剂后，紫外光照射60 min可使甲基红溶液降解完全，降解效率为未加入催化剂时的3倍.

Abstract: As the increase of environmental pollution and awareness of environmental protection, green chemistry is one of important direction of modern science. In recent years, heteropolyacids have been used as an efficient photocatalyst for the removal of organic pollutants. Ionic liquids have been applied in organic synthesis, electrochemistry, separation purification, and materials science because of their unique physical and chemical properties. The polyoxometalate-based ionic liquid hybrid material is a novel green catalyst containing the typical Keggin structure of heteropolyacids and ionic liquid cations, which possesses good water resistance, acidity, and is potential for efficient reaction from separation properties. Based on a model compound, organic dye methyl red (MR), the photocatalytic ability of the solid phase catalyst 1,3-bis(carboxymethyl)-imidazolium phosphotungstate was studied under UV light irradiation. The prepared catalyst was characterized by elemental analysis and IR spectra. The effects of irradiation time of UV light and amount of the catalyst to the degradation efficiency were investigated. The results showed that the synthesis photocatalyst retains both the Keggin structure of phosphotungstic anion and the structure of imidazolium cation. MR can undergo direct photolysis and the time required for complete photolysis was 220 min in the absence of the catalyst. When the amount of the catalyst was 0.02?0.10 g, the degradation efficiency of MR increased significantly with the increasing of the catalyst amount. The total degradation time of MR was 60 min when 0.08 g catalyst was added under UV light irradiation, and its degradation efficiency can reach three times as much as when no catalyst was added. The synthesized solid phase catalyst exhibited higher catalytic activity and good water resistance in the photolysis reactions. In addition, the catalyst was very stable and easily separated from the reaction system for recycling. It overcame the defects of traditional acid catalysts, which provided a promising new idea for high atom economy and green route of photocatalytic reactions.
