Pyrolyzing soft template-containing poly(ionic liquid)into hierarchical N-doped porous carbon for electroreduction of carbon dioxide
文献摘要：
Heteroatom-doped carbon materials have demonstrated great potential in the electrochemical reduction reaction of CO2(CO2RR)due to their versatile structure and function.However,rational structure control remains one challenge.In this work,we reported a unique carbon precursor of soft template-containing porous poly(ionic liquid)(PIL)that was directly synthesized via free-radical self-polymerization of ionic liquid monomer in a soft template route.Variation of the carbonization temperature in a direct pyrolysis process without any additive yielded a series of carbon materials with facile adjustable textural proper-ties and N species.Significantly,the integration of soft-template in the PIL precursor led to the formation of hierarchical porous carbon material with a higher surface area and larger pore size than that from the template-free precursor.In CO2RR to CO,the champion catalyst gave a Faraday efficiency of 83.0％and a current density of 1.79 mA·cm-2 at-0.9 V vs.reversible hydrogen electrode(vs.RHE).The abundant gra-phite N species and hierarchical pore structure,especially the unique hierarchical small-/ultra-micropores were revealed to enable better CO2RR performance.
