Synthesis of Mn-ZIF-67 for efficient degradation of tetracycline

Abstract

Antibiotics are extensively employed in the treatment of human and animal ailments. However, their excessive use and poor biodegradability have led to a notable accumulation of antibiotics in the environment, presenting potential health hazards to humans. In this study, tetracycline (TC) was selected as a representative antibiotic, and a recyclable material, Mn-ZIF-67, was synthesized to degrade TC through adsorption and peroxidase-like activity. Mn-ZIF-67 significantly enhances the peroxidase-like activity of ZIF-67. The removal efficiency of TC was boosted by 300% compared to ZIF-67 within a 10-min timeframe. With its high catalytic activity and stability, Mn-ZIF-67 exhibits significant promise for the swift degradation and elimination of antibiotics from the environment.
