A Zeolite-Templated Carbon Synthesized from Extralarge-Pore Zeolite ZEO-1

Abstract

A new member of the zeolite-templated carbon (ZTC) family with unprecedented properties has been developed using extralarge-pore zeolite ZEO-1 (JZO) as a template. The resulting ZTC-JZO exhibits strong X-ray diffraction long-range order, replicating three distinct zeolite planes with different lattice spacings. By harnessing the enhanced micropore void volume in the ZEO-1 template, we achieved the first ZTC with a bimodal micropore size distribution, resulting in superior skeleton density and thickness. The ZTC-JZO presents high electrical conductivity and demonstrates improved electrocatalytic activity in the oxygen reduction reaction.
