A micron-sized Co-MOF sheet to activate peroxymonosulfate for efficient organic pollutant degradation

A Co-MOF with a 2D morphology (BUC-92) was prepared, which exhibited outstanding rhodamine B (RhB) degradation performance via peroxymonosulfate (PMS) activation. RhB was degraded completely within 10 min in the presence of 0.2 g L-1 BUC-92 and 0.2 mM PMS, much higher than that using our previously reported MOF BUC-67 (54.4%) under the same conditions, whose composition was similar to that of BUC-92. A related mechanism was proposed. A fixed bed reactor was built to further evaluate the potential application of BUC-92.

Automated summary

In this study, a 2D co-metal organic framework (Co-MOF) named BUC-92 was prepared and exhibited remarkable degradation performance of rhodamine B (RhB) through peroxymonosulfate (PMS) activation. Complete degradation of RhB was achieved within 10 minutes in the presence of 0.2 g L-1 BUC-92 and 0.2 mM PMS, which was significantly higher than that of a similar composition Co-MOF BUC-67 previously reported.
