Photothermal-electrocatalysis interface for fuel-cell grade ammonia harvesting from the environment.

ABSTRACT: The development of sustainable artificial nitrogen recycling technologies enables ammonia extraction from ambient sources, facilitating zero-carbon Water-Energy-Food (WEF) Nexus integration. While electrochemical reduction of oxidized nitrogen offers promise for ammonia synthesis, purifying low-concentration products remains a challenge, limiting practical applications and undermining the Haber-Bosch process's viability. Here, we introduce a photothermal-electrocatalysis interface (PTEI) based on a Janus hybrid nanoarchitecture electrode, demonstrating synergistic enhancement in ammonia yield and evaporation performance. The photothermal-electrocatalysis interface-integrated system continuously produces and purifies ~2 M pure ammonia solution at up to 13.7 mg cm^-2 h^-1
