Mechanistic modeling of NO electrochemical reduction in a micro-tubular cell: Effects of CO2/H2O components and electrochemical promotion

New developments and challenges of solid oxide fuel cell (SOFC)-based technologies

“…In a recent mechanistic modeling study, the effects of H 2 O and CO 2 on NO removal were investigated. 22 Although H 2 O and CO 2 electrolysis could take place and compete with NO electrochemical reduction, the produced H 2 and CO can help reduce NO to N 2 chemically, leading to higher NO conversion. However, the presence of O 2 is unfavorable for NO removal as O 2 reduction proceeds much faster on Ni, Au, and Pt electrodes.…”

“…It was found that the presence of H 2 O and CO 2 could improve the conversion from NO to N 2 .

Development of NO_x Emission and Electrochemical Detection in Atmosphere

“…Do and Chen illustrated that the sensing properties of an amperometric NO gas sensor were significantly interfered by the presence of NO2 and SO2 in gas phase [40]. Xi et al studied the effects of CO2 and H2O on the NO conversion performance and revealed that the presence of CO2 and H2O are beneficial to the NO reduction [41]. Moreover, the improvement by H2O was stronger than that by CO2.…”
