Synthesis of ammonia directly from wet air at intermediate temperature

- For the first time, ammonia was synthesised from wet air at intermediate temperature.
- New catalyst Pr0.6Ba0.4Fe0.8Cu0.2O3−δ was synthesised for ammonia synthesis.
- The ammonia formation rate for wet air was just slightly lower than wet N2.
- The ammonia formation rate was 2 orders of magnitudes higher than reported values.
