Nanozymes have gained significant attention in the degradation of environmental pollutants due to their low cost and reusability. Peroxidase nanozymes, widely studied for pollutant degradation, are limited in the food industry due to hydrogen peroxide's potential damage to nutritional components. To address this, we designed a metal-organic framework material, Zirconium-Metalloporphyrin (PCN-222(Mn)), which integrates adsorption, enzyme catalysis, and photocatalysis activities. This system offers high specific surface areas for contaminant accumulation, superior laccase-like activities that eliminate the need for H
