Commercial indium-tin oxide glass: A catalyst electrode for efficient N2 reduction at ambient conditions

The typical Haber technical process for industrial NH 3 production involves plenty of energy-consumption and large quantities greenhouse gas emission. In contrast, electrochemical N 2 reduction proffers environment-friendly energy-efficient avenues to synthesize at mild conditions but demands efficient electrocatalysts the reaction (NRR). Herein we report first time that commercial indium-tin oxide glass (ITO/G) can be used as a catalyst electrode toward artificial fixation, it demonstrates excellent selectivity conditions. Such ITO/G delivers NRR performance with yield 1.06 × 10 −10 mol s −1 cm −2 faradaic efficiency 6.17% –0.40 V versus reversible hydrogen (RHE) in 0.5 M LiClO 4 . Furthermore, also possesses good stability durability. Finally, possible mechanism on ITO catalysts was explored using first-principles calculations. Commercial acts an electrocatalyst conversion , achieving high FE 6.17%.
