The study by Li et al. (2023) describes a novel method for continuous ammonia synthesis from nitrogen gas and water using contact electrification. The reaction occurs between protons in water and nitrogen adsorbed on the surface of polytetrafluoroethylene (PTFE) particles. Electron spin resonance (ESR) spectroscopy and density functional theory (DFT) calculations confirm that water acts as the proton donor for the reduction of nitrogen. The mechanism involves electron transfer and reduction processes driven by contact electrification, leading to the formation of ammonia. The optimal conditions for ammonia production include a pH of 6.5 to 7.0, ultrasonic power of 100 W, and a reaction temperature of 25 °C. Under these conditions, the ammonia production rate was approximately 420 μmol L⁻¹ h⁻¹ per gram of PTFE particles, with a rate stability of more than 90% over an 8-hour period. This method offers a sustainable alternative to the Haber–Bosch process, which is energy-intensive and carbon-intensive, by using water as the proton source instead of hydrogen. The findings suggest that contact electrification can be a promising approach for large-scale ammonia synthesis with low energy consumption and reduced environmental impact.The study by Li et al.
