Electrochemical reduction of nitrite (NO₂⁻) offers an energy-efficient route for ammonia (NH₃) synthesis and reduction of nitrite pollution. However, the near 100 % reaction selectivity has yet to be achieved due to the complicated reduction route. Here, we report that carbon dioxide (CO₂) can enhance the nitrite electroreduction to ammonia with near 100 % Faradaic efficiency on copper nanowire (Cu NW) catalysts in a broad potential range.

分子二氧化碳促进亚硝酸盐电还原为氨，法拉第效率接近统一

_{亚硝酸盐 (NO 2}^- ) 的电化学还原为合成氨 (NH ₃ ) 和减少亚硝酸盐污染提供了一种节能途径。然而，由于复杂的还原路线，尚未实现接近 100% 的反应选择性。在这里，我们报告了二氧化碳 (CO ₂ ) 可以在广泛的电位范围内以接近 100% 的法拉第效率在铜纳米线 (Cu NW) 催化剂上增强亚硝酸盐电还原为氨。
