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 Ea 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.
在本工作中，一种新型三维金属有机框架（MOF）已被合成并表征。该MOF在pH值范围为3至11的水溶液中表现出良好的化学稳定性。有趣的是，该MOF在无H2O2的可见光条件下对偶氮染料（MO、CR和CBR）的降解显示出高催化活性。MOF对MO、CR和CBR降解的Ea值分别为23.49、52.68和15.19 kJ mol-1。此外，MOF在催化过程中可重复使用，且催化活性无明显降低。
