Solid electrolyte potentiometry aided study of the selective catalytic reduction of nitric oxide on platinum catalysts

Solid Electrolytes: Applications in Heterogeneous Catalysis and Chemical Cogeneration

“…The need for an effective control of hazardous auto exhaust emissions led several research groups to use O 2− SECRs for the reaction of NO x with reducing compounds such as CO, ,, CH 4 , − C 2 H 4 , ,, C 3 H 6 , ,− ,,,− ,,, and NH 3 . , In most of the above works, NO x was fed at the cathode, together with the reducing compound, and the effect of O 2− pumping on the reaction rate was studied. The highest NEMCA effect was observed during the reduction of NO by C 3 H 6 on Rh when the rate enhancement factor (ρ) reached values as high as 150 …”

“…Several research groups examined the formation of products of the partial oxidation of propylene and compared the yields obtained in SECRs to those obtained in conventional catalytic reactors. Most of the works focused on the production of acrolein, ,,,,,− , followed by propylene oxide, ,,,, hexadiene and benzene, ,, and acrylic acid …”
