Effective improvement of sensing performance of amperometric NO2 sensor by Ag-modified nano-structured CuO sensing electrode

An amperometric-type NO2 sensor based on La10Si5AlO26.5 electrolyte and Ag-modified nano-structured CuO sensing electrode was proposed. Ag addition to CuO sensing electrode could remarkably increase sensor sensitivity and the best performance was observed at the CuO/Ag molar ratio of 1:0.5.
