In the present work, a new 3D metal–organic framework (MOF) has been synthesized and characterized. The MOF exhibits good chemical stability in aqueous solutions with the pH scale ranging from 3 to 11. Interestingly, the MOF shows high catalytic activities for the degradation of azo dyes (MO, CR and CBR) under visible light without H₂O₂. The E_a values of the MOF for MO, CR and CBR degradation are obtained to be 23.49, 52.68 and 15.19 kJ mol⁻¹, respectively. In addition, the MOF can be reused in the catalytic process without the catalytic activity decreasing obviously.

基于四苯乙烯咪唑配体的具有稳定MOF的可见光降解偶氮染料

在当前的工作中，已经合成并表征了一种新的3D金属-有机框架（MOF）。MOF在pH范围为3到11的水溶液中显示出良好的化学稳定性。有趣的是，MOF在无H ₂ O _2的可见光下对偶氮染料（MO，CR和CBR）的降解显示出高催化活性。得到的MO，CR和CBR降解的MOF的E _a值分别为23.49、52.68和15.19 kJ mol ^-1。此外，MOF可在催化过程中重复使用，而催化活性不会明显降低。
