What is AI-Based Nitrate-to-Ammonia Technology?

Why in News

China developed an AI-powered electrochemical technology to convert nitrate-rich wastewater into ammonia (NH3) for fertiliser production.

AI-Driven Catalyst Innovation

• The process uses an AI-optimised Dual-Atom Catalyst (DAC) containing two adjacent active metal atoms.
• The catalyst improves reaction selectivity and nitrate-to-ammonia conversion efficiency.
• The technology converts nitrates from agricultural runoff and industrial effluents into ammonia.

Energy-Efficient Ammonia Production 

• The technology uses electrochemical reduction to convert nitrates into ammonia at room temperature. 
• It is nearly three times more efficient than earlier nitrate-to-ammonia conversion methods. 
• Unlike the Haber-Bosch Process, it does not require high temperature and pressure conditions. 
  • The Haber-Bosch Process produces ammonia from nitrogen and hydrogen and is highly energy-intensive. 
• Ammonia is the main raw material for nitrogen fertilisers such as urea and ammonium compounds.
