Spatial confinement of sliver nanoparticles in nitrogen-doped carbon framework with high catalytic activity and long-term cycling

Abstract

Graphical AbstractWe prepared a Ag NP@N-C-900 catalyst by a in-situ assisted spatial confinement method. This obtained Ag NP@N-C-900 possesses superior ORR performance with a half-wave potential of 0.83 V, excellent stability and methanol resistance ability. Attractively, the primary zinc–air battery based on the Ag NP@N-C-900 air-cathode offers a long cycle of 3600 minutes as well as excellent durability. The catalytic activity and stability exceed most of the Ag-based catalysts reported so far, and are completely comparable to commercially available Pt/C.
