A gas–liquid switching reaction system for normothermic photo-driven chemical looping ammonia synthesis

Key Points

• The study investigates a new system for synthesizing ammonia using a photo-driven process under normal conditions.
• Developed a gas-liquid switching reaction system (GLS) using metal oxides
• Evaluated the ammonia production rate on TiO2
• Utilized alternating N2 and H2O coverage for the synthesis
• Achieved an NH3 production rate of 1.48 mmol g−1 h−1 on TiO2
• Demonstrated successful operation under ambient conditions
• Showed the feasibility of a green ammonia synthesis approach
