Background:

Electrocatalytic nitrogen reduction reaction (NRR) offers a sustainable alternative to the Haber-Bosch process for ammonia synthesis.
Developing efficient electrocatalysts with high ammonia yield rates and Faradaic efficiency is crucial for ambient NRR.
Copper-based materials are investigated for their potential in multi-electron reduction reactions, though often struggle with hydrogen evolution.

Purpose of the Study:

To prepare and characterize novel Cu-based nanowire array (NA) catalysts on Cu foam (CF) substrates for electrocatalytic NRR.
To evaluate the performance of various Cu-based NAs (Cu(OH)2, Cu3N, Cu3P, CuO, Cu) as self-supported electrodes for NH3 production.
To elucidate the role of catalyst surface structure in enhancing NRR performance.

Main Methods:

In situ growth of Cu-based nanowire arrays (NA) on Cu foam (CF) substrates.
Electrochemical characterization of NRR performance, including ammonia yield rate and Faradaic efficiency (FE).
Surface analysis using contact angle measurements and simulated calculations.

Main Results:

CuO NA/CF exhibited a maximum NH3 yield rate of 1.84 × 10^-9 mol s^-1 cm^-2.
Cu NA/CF achieved a peak FE of 18.2% for NH3 production at -0.1 V vs RHE.
The superaerophobic surface structure of the NAs was identified as critical for efficient NRR.

Conclusions:

Cu-based nanowire arrays, particularly CuO NA/CF and Cu NA/CF, are effective electrocatalysts for NRR under ambient conditions.
The developed catalysts surpass the performance of many previously reported metal-based NRR electrocatalysts.
Surface properties, such as superaerophobicity, significantly influence the efficiency of electrocatalytic ammonia synthesis.
