Catalytic activity study of a laccase-like copper–gallic acid MOF and its applications in the colorimetric determination of norepinephrine and degradation of environmental pollutants

Abstract

and superior recyclability compared with laccase at the same mass concentration. Remarkably, Cu-GA MOF displayed exceptional thermal tolerance maintaining substantial catalytic activity at temperatures up to 90 °C. In contrast to natural enzymes, Cu-GA MOF exhibited enhanced stability and recyclability underscoring its potential for diverse bio-applications. These findings highlight the promising role of Cu-GA MOF as a robust and versatile catalyst in biocatalytic and analytical applications.
