Producing ammonia using less energy

Scientists at the Tokyo Institute of Technology have developed an improved catalyst facilitating the synthesis of ammonia at merely 50°C (when conventional techniques require temperatures of 450°C).

Ammonia is commonly used as a refrigerant (known as R717). Its production is typically carried out  through the Haber process, which converts atmospheric nitrogen to ammonia by a reaction with hydrogen under high temperatures and pressures (between 400 °C and 500 °C and 15-25 MPa).
