Coupling calcination with sulfidation strategy to fabricate a hydrophilic bimetallic transition nanozyme for boosting antibacterial efficiency

Abstract

In this study, we coupled calcination with sulfidation of a Prussian blue analog precursor to construct a hydrophilic CoS₂/FeS₂@NCF nanozyme. The nanozyme was observed to display exceptionally high peroxidase-like activity, with inhibition rates against E. coli and S. aureus reaching 99.9%. This strategy not only offers a novel approach for synthesizing high-performance nanozymes but also demonstrates their considerable potential in antibacterial applications.
