Nitrogen-free commercial carbon cloth with rich defects for electrocatalytic ammonia synthesis under ambient conditions†
Abstract
Nitrogen-free commercial carbon cloth treated at 450 °C in air possesses abundant defects, exhibiting superior electrocatalytic activity for the nitrogen reduction reaction (NRR) with an NH3 yield of 2.59 × 10−10 mol cm−2 s−1 and a Faradaic efficiency of 6.92% at −0.3 V (vs. RHE) in 0.1 M Na2SO4 + 0.02 M H2SO4.
