The invention belongs to the technical field of materials, and discloses an enzyme-immobilized composite material and a preparation method. The method includes the following operation steps: firstly combining the original carrier with carbon nanotubes, then chelating with Cu 2+ to obtain a carrier with improved performance, and then using the carrier with improved performance to immobilize the enzyme to obtain an immobilized enzyme. The modification method of the invention improves the performance of the carrier material, can obtain a larger enzyme load and a higher enzyme activity, and uses the carrier to immobilize the laccase to improve the thermal stability, pH stability and operational stability of the enzyme. and storage stability, and enhances the adsorption and degradation ability of immobilized enzymes to natural and synthetic dyes, phenols and their derivatives, endocrine disruptors, drugs and pesticides and other pollutants, and enhances the industrial application of immobilized enzymes. |
