Electrochemical ammonia synthesis is one of the sustainable technologies to artificially synthesize ammonia because of its reduced energy consumption and environmental friendliness. Nevertheless, the low ammonia yield and poor selectivity of the nitrogen reduction reaction limit its large-scale industrial applications. Herein, mesoporous RhRu film on nickel foam (mRhRu/NF) is synthesized by electrodeposition using a diblock copolymer as a soft template. The introduction of the Ru element with a high nitrogen adsorption energy into mesoporous Rh film significantly improves the catalytic performance due to the electronic effect and binder-free mesoporous structure. In a neutral solution, the mRhRu/NF shows a high ammonia production rate of 30.28 μg h−1 mgcat−1 and a Faraday efficiency of 28.33%. This research offers an inspiring route for the rational synthesis of self-supported mesoporous alloys for active NRR.

用于电催化氮还原成氨的双金属介孔 RhRu 薄膜

电化学合成氨具有能耗低、环境友好等优点,是人工合成氨的可持续技术之一。然而,氮还原反应的氨产率低和选择性差限制了其大规模的工业应用。在此,使用二嵌段共聚物作为软模板,通过电沉积合成镍泡沫上的介孔 RhRu 膜 (mRhRu/NF)。由于电子效应和无粘合剂的介孔结构,将具有高氮吸附能的Ru元素引入介孔Rh薄膜中,显着提高了催化性能。在中性溶液中,mRhRu/NF 显示出 30.28 μg h -1 mg cat -1的高氨产率法拉第效率为 28.33%。该研究为合理合成用于活性 NRR 的自支撑介孔合金提供了一条鼓舞人心的途径。
