Octopus-like PtCu nanoframe as peroxidase mimic for phenol removal

In this study, uniform octopus-like platinum-copper alloy nanoframes (OPCANs) were exploited as peroxidase mimics for phenol removal. The OPCANs exhibited excellent peroxidase-like catalytic activity with oxidant H2O2. Compared with the natural peroxidase horseradish peroxidase (HRP), OPCANs could catalyze H2O2 over a wider range of temperatures and pH values. Moreover, the OPCANs displayed a splendid phenol removal over 80% after a 30 min period of reaction.
