Promoting Electrocatalytic CO2 Reduction to CO via Sulfur‐Doped Co‐N‐C Single‐Atom Catalyst^†

Chinese Journal of Chemistry, Год журнала: 2023, Номер 41(24), С. 3553 - 3559

Comprehensive Summary Electrocatalytic reduction of CO 2 to fuels and chemicals possesses huge potential alleviate current environmental crisis. Heteroatom doping in metal‐nitrogen‐carbon (M‐N‐C) single‐atom catalysts (SACs) has been found be capable promote the electrocatalytic reaction (CO RR). However, origin enhanced activity is still elusive. Here, we report that sulfur‐doped cobalt‐nitrogen‐carbon catalyst (Co 1 ‐SNC) exhibits superior RR performance compared sulfur‐free counterpart ‐NC). On basis situ attenuated total reflectance surface‐enhanced infrared absorption spectroscopy (ATR‐SEIRAS), kinetic isotope effect (KIE) theoretical calculation, it demonstrated sulfur can water activation, elevate d‐band center Co active site, reduce free energy *COOH intermediate formation. This work deepens understanding chemistry over heteroatom‐doped SACs for designing efficient processes.

Abstract CO 2 reduction is a highly attractive route to transform into useful feedstocks, of which C products are more desired than 1 , yet face high kinetic barriers C−C electrocoupling. Here, the engineering pore‐enabled local confinement reaction environments reported for tuning enrichment surface‐adsorbed oxygen‐relevant species and establishment their pronounced benefits in promoting coupling over oxide‐derived Cu‐based catalysts. A new approach utilizing microphase separation block copolymer developed fabricate bicontinuous mesoporous CuO nanofibers (CuO‐BPNF). The enhanced from long‐range mesochannels enables adsorption OH ad /O on Cu surface at wide negative potential range −0.7 – −1.3 V reduction, cannot be achieved conventional deficient short‐range pores. Constant‐potential DFT calculations reveal that surface‐bound oxygen weakens *CO affinity with (111) lowers both *CO−CO dimerization hydrogenation enable *CO−CHO coupling. Accordingly, ‐to‐C Faradaic efficiency 74.7% CuO‐BPNF shown, significantly larger counterparts This work offers general design principle manage reactive steering pathways interfacial catalysis.

Active hydrogen-controlled CO₂/N₂/NO_x electroreduction:From mechanism understanding to catalyst design

The Innovation Materials, Год журнала: 2024, Номер 2(1), С. 100058 - 100058

Опубликована: Янв. 1, 2024

<p>The development of renewable-energy-powered electrocatalysis meets the need for sustainable society. With water as proton source, it enables efficient production chemicals and fuels from renewable resources like CO₂, N₂, NO_x under ambient conditions. Hydrogen generated via dissociation is a crucial participant in transforming reactants into desired products, but also serves direct source undesired reactions when excess. In this review, we first present an overview functional mechanisms active hydrogen electroreduction CO₂/N₂/NO_x. We then introduce range methods to enhance our understanding these mechanisms. Furthermore, detailed discussion design strategies aimed at regulating reduction CO₂/N₂/NO_x provided. Finally, outlook on critical challenges remaining research area promising opportunities future considered.</p>
