We present a facile synthetic method that yields Ag@CoxP core–shell-type heterogeneous nanostructures with excellent oxygen evolution reaction (OER) activity. This nanocatalyst can deliver current density of 10 mA/cm2 at small overpotential 310 mV and exhibits high catalytic stability. Additionally, the activity is 8 times higher than Co2P nanoparticles, owing primarily to strong electronic interaction between Ag core CoxP shell.
