The polyoxometalate-imidazole ionic liquids(POM-ILs) with low melting points at 94.5 and 95.5℃, [Cnmim]4[Mo8O26](Cnmim=1-alkyl-3-methylimidazolium, n=12,14), have been successfully synthesized and charac-terized by DSC, single-crystal X-ray diffraction and TGA, etc. The two POM-ILs have relatively high stability with decomposing temperature up to about 347 and 344℃, respectively. Further photocatalytic performance was mea-sured via the degradation of rhodamine B(RB) in aqueous solution. The experiments show that the conversion reached to 90% after 90 min under UV-light and the degradation efficiency depended on pH value, different dosages and so on. In addition, the catalysts can be recycled for several times without significant loss of activity.
