In situ synthesis of ultrathin metal–organic framework nanosheets: a new method for 2D metal-based nanoporous carbon electrocatalysts

Abstract

Ultrathin ZIF-67 nanosheets are synthesized for the first time <italic>via</italic> a salt-template confined <italic>in situ</italic> growth strategy. And the directly carbonized Co,N-doped nanoporous carbon nanosheets greatly boost the oxygen reduction reaction (ORR) as well.
