Bimetallic nanozymes have been emerging as essential catalysts due to their unique physicochemical properties from the monometallics. However, access optimize catalytic performance is often limited by thermodynamic immiscibility and also heterogeneity. Thus, we present a one-step coreduction strategy prepare miscible Cu-Pd bimetallic with controllable shape homogeneously alloyed structure. The homogeneity systematically explored luckily, homogeneous introduction of Cu successfully endows enhanced Fenton-like efficiency. Density functional theory (DFT) theoretical calculation reveals that exhibit smaller d-band center compared Pd nanozymes. Easier adsorption H
