Degradation of azo dyes under visible light with stable MOF based on tetrastyrene imidazole ligand

Abstract

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.
