Kinetics and Mechanisms for Nanozymes

Abstract

The catalytic behaviors, kinetics, and mechanisms are the basic criteria to determine if a nanomaterial with intrinsic activity is a nanozyme. Michaelis–Menten model is usually used to analyze the kinetics parameters including affinity constant, reaction velocity, and catalytic efficiency for natural enzymes. Nanozymes follow similar kinetics and mechanisms as natural enzymes. However, the active sites and detailed physiochemical processes responsible for the catalysis in nanomaterials may be different, regarding the features including composition, crystal structure, defects, electron transfer, substrate adsorption, and product dissociation. There may be common nature for the catalysis of nanozymes and natural enzymes.
