Optimization of an electrochemical cell with an adsorption layer for NOx removal
The structure of a multilayer electrochemical cell with an adsorption layer was optimized by removing an yttriastabilized zirconia cover layer. It was found that the NOx removal properties of the electrochemical cell were dramatically enhanced through the optimization, especially under conditions of low voltage, intermediate temperature, and high O2 concentration.
The pronounced increase in activity and selectivity for NOx decomposition after removing the ytrriastabilized zirconia cover layer was attributed to the extensive release of selective reaction sites for NOx species and a strong promotion for NOx reduction from the interaction of the directly connected adsorption layer with both the Pt and catalytic layers.
The optimized electrochemical cell may provide a promising solution for NOx emission control.
