Nanoparticulate Peroxidase/Catalase Mimetic and Its Application

Abstract

Ru sitting comfortably: Ruthenium oxide nanoparticles show bienzyme-like activities, and are capable of catalyzing H(2)O(2) disproportionation at pH 7.0 and peroxidation at pH 4.0 in aqueous solutions (see scheme). Their specific activities are better than many natural catalases and peroxidases and far better than bifunctional catalase/peroxidases.
