Electrodeposited CoP2 on CO2-laser-modified graphite felt: a robust electrocatalyst for nitrite reduction to ammonia

This study presents a CoP 2 /GO–GF electrocatalyst synthesized via CO 2 laser and electrodeposition, achieving superior NO 2 RR. Enhanced reaction kinetics and high Faradaic efficiency (∼80%) enable outstanding NH 3 yield (10.6 mg h −1 cm −2 ) and durability.
