Dr. Jalili says his team was able to make ammonia this way at an ambient 25°C, less than 10% of the temperature required to make ammonia the conventional way via the Haber-Bosch method.

研究人员针对传统Haber-Bosch工艺高能耗问题，开发了仿生Fe2 V4 O13 /Mo2 S3 三元催化剂，通过缺陷工程实现N2 RR（氮还原反应）高效转化，在-0.7 V vs. RHE下获得47.6%法拉第效率（FE）和5.46 mg h-1 cm-2 的NH3 产率，接近CSIRO能源标准（6.12 mg h-1 cm-2 ），为绿色氨合成提供新策略。

本研究针对可再生能源波动性问题，系统评估了绿色氨 (NH3 )与氢 (H2 )作为能源载体的往返效率。通过分析水电解电压 (1.48-1.84V)对Haber-Bosch工艺能耗的影响，发现将电解电压降至1.50V可使绿色氨生产能耗与灰氨相当。研究证实，采用燃气轮机联合循环 (GTCC)时，绿色氨和氢的最高往返效率分别达42%和52% ...
