Abstract Compared to modern fossil‐fuel‐based refineries, the emerging electrocatalytic refinery (e‐refinery) is a more sustainable and environmentally benign strategy convert renewable feedstocks energy sources into transportable fuels value‐added chemicals. A crucial step in conducting e‐refinery processes development of appropriate reactions optimal electrocatalysts for efficient cleavage formation chemical bonds. However, compared well‐studied primary (e.g., O 2 reduction, water splitting), mechanistic aspects materials design complex are yet be settled. To address this challenge, herein, we first present fundamentals heterogeneous electrocatalysis some reactions, then implement these establish framework by coupling situ generated intermediates (integrated reactions) or products (tandem reactions). We also set principles strategies efficiently manipulate reaction pathways.

Oxidation State Modulation of Bismuth for Efficient Electrocatalytic Nitrogen Reduction to Ammonia

Advanced Functional Materials, Год журнала: 2021, Номер 31(30)

Опубликована: Май 24, 2021

Abstract Electrocatalytic nitrogen reduction reaction (NRR) is a promising strategy for ammonia (NH 3 ) production under ambient conditions. However, it severely impeded by the challenging activation of NN bond and competing hydrogen evolution (HER), which makes crucial to design electrocatalysts rationally efficient NRR. Herein, rational bismuth (Bi) nanoparticles with different oxidation states embedded in carbon nanosheets (Bi@C) as NRR reported. The performance Bi@C improves increase Bi 0 /Bi 3+ atomic ratios, indicating that state plays significant role electrochemical synthesis. As result, annealed at 900 ° C optimal demonstrate best high NH yield rate remarkable Faradaic efficiency 15.10 ± 0.43% − 0.4 V versus RHE. Density functional theory calculations reveal effective modulation can tune p ‐filling active sites strengthen adsorption *NNH, boost potential‐determining step facilitate electrocatalytic This work may offer valuable insights into material modulating electrocatalysis.
