Abstract:
Surface regulation is an effective strategy to improve the performance of catalysts, but it has been rarely demonstrated for nitrogen reduction reaction (NRR) to date. Now, surface‐rough Rh 2 Sb nanorod (RNR) and surface‐smooth Rh 2 Sb NR (SNR) were selectively created, and their performance for NRR was investigated. The high‐index‐facet bounded Rh 2 Sb RNRs/C exhibit a high NH 3 yield rate of 228.85±12.96 μg h −1 mg −1 Rh at −0.45 V versus reversible hydrogen electrode (RHE), outperforming the Rh 2 Sb SNRs/C (63.07±4.45 μg h −1 mg −1 Rh ) and Rh nanoparticles/C (22.82±1.49 μg h −1 mg −1 Rh ), owing to the enhanced adsorption and activation of N 2 on high‐index facets. Rh 2 Sb RNRs/C also show durable stability with negligible activity decay after 10 h of successive electrolysis. The present work demonstrates that surface regulation plays an important role in promoting NRR activity and provides a new strategy for creating efficient NRR electrocatalysts.
