Efficient urea electrosynthesis from nitrite and CO2 reduction on single W atom catalyst
Electroreduction of CO2 and NO2− to urea (ECNU) provides a fascinating method for concurrently migrating polluted NO2− and producing value-added urea. In this study, atomically dispersed W on MoS2 (W1/MoS2) is designed as an efficient ECNU catalyst, which exhibits the highest Faraday efficiency of 60.11 % and urea yield rate of 35.80 mmol h−1 g−1 in flow cell. Atomic characterizations reveal that W single atoms exist as isolated W1-S3 moieties on MoS2. Combined theoretical calculations and operando spectroscopic measurements demonstrate that the enhanced ECNU performance of W1/MoS2 arises from the construction of W1-S3 moieties that can promote CN coupling and hydrogenation energetics, whilst suppressing the competing side reactions.
