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

Ag @ Co _x P核-壳多相纳米粒子作为高效氧释放反应催化剂

我们提出了一种简便的合成方法，该方法可产生具有出色的氧释放反应（OER）活性的Ag @ Co _x P核-壳型异质纳米结构。该纳米催化剂在310mV的小的过电势下可以提供10mA / cm ²的电流密度，并且表现出高的催化稳定性。另外，Ag @ Co _x P的催化活性比Co ₂ P纳米颗粒的催化活性高8倍，这主要归因于Ag核与Co _x P壳之间的强电子相互作用。
