Design of graphitic multichannel monolith electrode with in-situ transformed Ni-N-C sites for continuous electrolysis of CO₂

Abstract            

    The stable and continuous electrolysis of CO₂ is attracting increasing attention for fundamental research and potentially practical applications. However, it remains challenging to address the issues of limited CO₂ supply and vulnerable interphase structure for most electrode configurations. Herein, we designed a multichannel monolith electrode, and the channel walls are composed of active phases of nickel and nitrogen co-doped carbon (Ni-N-C) sites that are in-situ formed during electrode preparations. Such multichannel monolith electrode design not only strengthens the continuous vapor-fed CO₂ flowing to triple-phase interfaces, but also promotes electron transfer, thereby accelerating CO₂ electroreduction. Exemplified by the electrolysis reaction of CO₂ to CO, the graphitic Ni-N-C multichannel monolith electrode delivered a maximum CO Faradaic efficiency of up to 94% and a CO productivity of 139.5 L g_cat^-1 h^-1 in a stable operation. Moreover, the design principles of novel multichannel monolith electrode can be extended to other gas-consuming reactions such as O₂ reduction. This work represents a cost-effective and convenient alternative electrode design for gas-involving electrochemical reactions, which may also be applicable to other electrochemical energy conversion fields.
