Abstract

Abstract: Herein we introduce a straightforward, low cost, scalable, and technologically relevant method to manufacture an all‐carbon, electroactive, nitrogen‐doped nanoporous‐carbon/carbon‐nanotube composite membrane, dubbed "HNCM/CNT". The membrane is demonstrated to function as a binder‐free, high‐performance gas diffusion electrode for the electrocatalytic reduction of CO2 to formate. The Faradaic efficiency (FE) for the production of formate is 81 %. Furthermore, the robust structural and electrochemical properties of the membrane endow it with excellent long‐term stability. Abstract : Carbon in carbon : A versatile and straightforward method was introduced to fabricate N‐doped hierarchical‐carbon/carbon‐nanotube membrane, which can be directly utilized as a highly active, selective, and stable diffusion electrode for CO2 reduction to formate in aqueous media.
