Defective TiO 2- x for High-Performance Electrocatalytic NO Reduction toward Ambient NH 3 Production
Synthesis of green ammonia (NH ) via electrolysis of nitric oxide (NO) is extraordinarily sustainable, but multielectron/proton-involved hydrogenation steps as well as low concentrations of NO can lead to poor activities and selectivities of electrocatalysts. Herein, it is reported that oxygen-defec...

| description | Synthesis of green ammonia (NH
) via electrolysis of nitric oxide (NO) is extraordinarily sustainable, but multielectron/proton-involved hydrogenation steps as well as low concentrations of NO can lead to poor activities and selectivities of electrocatalysts. Herein, it is reported that oxygen-defective TiO
nanoarray supported on Ti plate (TiO
/TP) behaves as an efficient catalyst for NO reduction to NH
. In 0.2 m phosphate-buffered electrolyte, such TiO
/TP shows competitive electrocatalytic NH
synthesis activity with a maximum NH
yield of 1233.2 µg h
cm
and Faradaic efficiency of 92.5%. Density functional theory calculations further thermodynamically faster NO deoxygenation and protonation processes on TiO
(101) compared to perfect TiO
(101). And the low energy barrier of 0.7 eV on TiO
(101) for the potential-determining step further highlights the greatly improved intrinsic activity. In addition, a Zn-NO battery is fabricated with TiO
/TP and Zn plate to obtain an NH
yield of 241.7 µg h
cm
while providing a peak power density of 0.84 mW cm
