One step pyrolysis synthesis of silver/nitrogen-doped carbon sheet for oxygen reduction in alkaline media
We developed the silver supported on nitrogen-doped carbon sheets (Ag/NC) synthesized by simple one-pot and in-situ thermal treatment as an efficient ORR catalyst. The Ag/NC exhibits higher activity than NC in terms of onset potential and half-wave potential. The kinetic parameters confirm 4e(-) reaction pathway for ORR on Ag/NC. In addition, the Ag/NC also shows better methanol tolerance and superior durability than Pt/C in alkaline solution. (C) 2017 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
