Summary Artificial N2 fixation is one of the most important industrial processes for human beings. However, current Haber-Bosch process based on fossil fuel suffers from unsustainability and a low to NH3 conversion. Here, we report magnesium chloride cycle synthesis H2O at atmospheric pressure. In this cycle, reacts with Mg form Mg3N2. Cl2 are produced by electrolysis molten MgCl2. NH4Cl used h...
