AI Technical Summary
Technical Problem
The Fe(II)/Fe(III) cycle within the FeS structure of existing heterogeneous Fenton catalysts is hindered, which limits their application in heterogeneous Fenton reactions and makes it difficult to efficiently remove antibiotic pollutants from water.
Method used
A bimetallic catalyst, copper-doped ferrous sulfide, supported on ceramic particles, is used to drive the Fe(II)/Fe(III) cycle through the catalytic effect of Cu, thereby realizing the internal iron cycle of FeS. The preparation process is simple and highly stable.
Benefits of technology
It achieves efficient activation by H2O2, effectively removing the antibiotic ciprofloxacin from water. The catalyst has a stable structure, extended service life, and significantly improved degradation effect.
