Strong substrate affinity and high catalytic efficiency are persistently pursued to generate high-performance nanozymes. Herein, with unique surface atomic configurations distinct d-orbital coupling features of different metal components, a class highly efficient MnFeCoNiCu transition high-entropy nanozymes (HEzymes) is prepared for the first time. Density functional theory calculations demonstrate that improved between metals increases electron density near Fermi energy level (EF ) shifts position overall d-band center respect EF , thereby boosting site-to-site transfer while also enhancing adsorption oxygen intermediates during catalysis. As such, proposed HEzymes exhibit superior affinities efficiencies comparable natural horseradish peroxidase (HRP). Finally, superb (POD)-like activity used in biosensing antibacterial applications.
