Stress induced to shrink ZIF-8 derived hollow Fe-NC supports synergizes with Pt nanoparticles to promote oxygen reduction electrocatalysis

Here, we have successfully structured Pt NPs on stress-induced to shrink ZIF-8 derived hollow Fe-NC supports, and the obtained Pt@Fe-NC catalyst enhanced the ORR performance due to the interaction between Pt NPs and Fe-NC supports leading to the reduced adsorption of *OH intermediates.
