Green ammonia is a crucial green energy source. Here, our team has developed a direct air-capture electrochemical reduction technology that operates under ambient conditions. By activating air with plasma, we obtain a precursor solution that is electrochemically reduced to produce green ammonia for broad applications. This technology transforms ubiquitous air into high-value chemicals, bypassing the need for nitrogen separation, green hydrogen, and high-temperature/high-pressure conditions.

This technology integrates five core technologies, including air plasma capture, thin-film electrocatalyst, NOx electroreduction, glycerol/furfural anodic oxidation, and acid-capture ammonia purification. The breakthrough lies in the innovative path of efficient N-O bond generation, material optimization, and highly selective electrical reduction, which combine low energy consumption and high Faraday efficiency, to realize the direct conversion of air into high-value ammonia products.

Our technology uses air plasma capture and electrochemical reduction to prepare green ammonia for fertilizers, ammonia fuels, hydrogen storage carriers, the low-carbon chemical industry, and resource recycling. At the 2025 World Economic Forum, "green" nitrogen fixation technology was among the top 10 emerging technologies, indicating that our technology is at the forefront globally and is expected to drive market value for low-carbon chemicals and the emerging green ammonia industry.
