Abstract

Spinel-type CoMn2O4 materials are promising catalyst for heterogeneous activation of peroxymonosulfate (PMS), but the catalytic activity still need considerable improvements for practical environmental application and the underlying Co-Mn synergy is unclear. In this work, we synthesized CoMn2O4 microplates by using CoMn2-perylene-3,4,9,10-tetracarboxylic dianhydride (ptcda) metal organic frameworks (MOFs) as the precursor. The resulting material showed significantly higher catalytic activity for the PMS activation and sulfanilamide (SA) degradation than the CoMn2O4 obtained by conventional solvothermal synthesis methods, due to its much higher specific surface area and abundant surface hydroxyl groups as the active sites. In addition, the Co-Mn synergy in the synthesized material for the efficient heterogeneous catalysis was elucidated. The catalyst stability was also evaluated. Our work may lay the foundation for optimized design of highly-efficient heterogeneous catalyst for environmental application.
