Findings on Nanoparticles Reported by Investigators at Chengdu University (Niwo4 Nanoparticles With Oxygen Vacancies: High-efficiency Electrosynthesis of Ammonia With Selective Reduction of Nitrite)

Article Description

Electrochemical reduction of nitrite (NORR) is a promising research direction for removing environmental pollutants NO from wastewater and generating value-added ammonia (NH). However, NORR kinetic reactivity is slow and requires high-efficient electrocatalysts. In the present study, we report C-NiWO nanoparticles grown on nickel foam as efficient catalysts. The NH yield of C-NiWO/NF in 0.1 M NaOH containing 0.1 M NO was 10 974.36 μg h cm at −0.4 V with a Faraday efficiency of 97.6%. Notably, a Zn-NO battery with a C-NiWO/NF as cathode has a high peak power density of 5.55 mW cm and provides a simultaneous NH yield of 2194.54 μg h cm. In addition, theoretical calculations revealed the NORR mechanism of C-NiWO/NF.
