Abstract:
Nitrite (NO 2 − ) is a detrimental pollutant widely existing in groundwater sources, threatening public health. Electrocatalytic NO 2 − reduction settles the demand for removal of NO 2 − and is also promising for generating ammonia (NH 3 ) at room temperature. A nanotube array directly grown on a current collector not only has a large surface area, but also exhibits improved structural stability and accelerated electron transport. Herein, a self-standing FeOOH nanotube array on carbon cloth (FeOOH NTA/CC) is proposed as a highly active electrocatalyst for NO 2 − -to-NH 3 conversion. As a 3D catalyst, the FeOOH NTA/CC is able to attain a surprising faradaic efficiency of 94.7% and a large NH 3 yield of 11937 μg h −1 cm −2 in 0.1 M PBS (pH = 7.0) with 0.1 M NO 2 − . Furthermore, this catalyst also displays excellent durability in cyclic and long-term electrolysis tests.
