Abstract

Although nanozymes are promising substitutes for natural enzymes due to their exceptional stability, low cost, and activity tunability, peroxidase (POD)-mimicking metal oxides like Co3O4 are often limited by its moderate intrinsic activity. In this study, phosphorus-doped Co3O4 nanofibers (P-Co3O4 NFs) are synthesized via electrospinning and calcination. Optimizing the P incorporation level yields…
