Abstract Nanozymes capable of generating reactive oxygen species have recently emerged as promising treatments for wounds infected with drug‐resistant bacteria, possessing a reduced possibility inducing resistance. However, the therapeutic effect is limited by shortage endogenous oxy‐substrates and undesirable off‐target biotoxicity. Herein, ferrocenyl coordination polymer (FeCP) nanozyme, featuring pH switchable peroxidase (POD)‐ catalase (CAT)‐like activity incorporated indocyanine green (ICG) calcium peroxide (CaO 2 ) to fabricate an H O /O self‐supplying system (FeCP/ICG@CaO precise treatment bacterial infections. At wound site, CaO reacts water generate . Acting POD mimic under acidic microenvironment, FeCP catalyzes into hydroxyl radicals prevent infection. switches CAT‐like in neutral tissue, decomposing oxidative damage facilitate healing. Additionally, FeCP/ICG@CaO shows photothermal therapy capability, ICG can emit heat near‐infrared laser irradiation. This assists fully exerting its enzyme‐like activity. Thus, this achieves antibacterial efficiency 99.8% vitro effectively overcomes main limitations nanozyme‐based assays, resulting satisfactory effects repairing normal special skin tumor bacteria.
