Ruthenium Anchored Laser-Induced Graphene as Binder-Free and Free-Standing Electrode for Selective Electrosynthesis of Ammonia from Nitrate.

ABSTRACT: Developing effective electrocatalysts for the nitrate reduction reaction (NO₃RR) is a promising alternative to conventional industrial ammonia (NH₃) synthesis. Herein, starting from a flexible laser-induced graphene (LIG) film with hierarchical and interconnected macroporous architecture, a binder-free and free-standing Ru-modified LIG electrode (Ru-LIG) is fabricated for electrocatalytic NO₃RR via a facile electrodeposition method. The relationship between the laser-scribing parameters and the NO₃RR performance of Ru-LIG electrodes is studied in-depth. At -0.59 V_RHE, the Ru-LIG electrode exhibited the optimal and stable NO₃RR performance (NH₃ yield rate of 655.9 µg cm^-2 h^-1 with NH₃
