This study exposes, for the first time, the effect of Electrochemical Promotion (EPOC) by potassium cations on Pt catalyst for low temperature CO oxidation process. The effect of catalyst polarization drastically increased the catalytic rate for more than 11 times by decreasing the light-off temperature by almost 40°C. The promotional phenomenon was found to be reversible due to the formation and...
Copper ion-exchanged solids prepared by the modified sol–gel method with different percentage of the organic and inorganic silicoaluminate, and with a 25% of zeolite ZSM-5, were studied as catalysts for the selective catalytic reduction of NO by propene in the presence of oxygen and water. The solids without zeolite were active for this reaction, but showed a poor performance under wet conditions...
