Abstract

Smart nanomaterials that can simultaneously detect and eliminate contaminants in water environment are significant for health protection. To achieve such goal, Co-MOF-74 was in-situ assembled on regenerated cellulose membranes followed by calcination process, thus achieving dual-functional Co₃O₄/cellulose derivative membrane (Co₃O₄/CDM) catalyst. The Co₃O₄ morphology was readily controlled by further recrystallization of the deposited MOF precursor. Combining the high enrichment ability of cellulose membrane and outstanding peroxidase-active of Co₃O₄, the fast color reaction for phenol was accomplished within 10 min by Co₃O₄/CDM with the assistance of H₂O₂ and 4-aminoantipyrine (4-AAP). Moreover, the Co₃O₄/CDM also portrayed an excellent degradation property for phenol elimination via sulfate radical-advanced oxidation processes (SR-AOPs). The degradation efficiency of phenol reached 93% in 20 min, and the possible mineralization mechanism was proposed based on the XPS and LC-MS analysis. Thus, Co-MOF-74 derived Co₃O₄/CDM shows excellent properties in aiding the colorimetric detection and degradation of phenol in aqueous solutions.
