 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 Rh2Sb nanorod (RNR) and surface-smooth Rh2Sb NR (SNR) were selectively created, and their performance for NRR was investigated. The high-index-facet bounded Rh2Sb RNRs/C exhibit a high NH3 yield rate of 228.85±12.96 μg h−1 mg−1 Rh at −0.45 V versus reversible hydrogen electrode (RHE), outperforming the Rh2Sb 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 N2 on high-index facets. Rh2Sb 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. © 2020 Wiley-VCH Verlag GmbH & Co.
