The selective oxidation of CO in the presence of H2O and CO2 has been studied on Pt supported on different zeolitic materials (MOR, ZSM-5, FAU and ETS-10) using a range of operating conditions and a variety of characterization techniques. The behavior of the Pt–ETS-10 and Pt–FAU catalysts has been investigated in more depth and the results obtained have been compared and related to the different characteristics of the supports. The best results in the presence of H2O and CO2 were obtained with Pt–FAU catalysts, showing stable catalytic activity and complete conversion of CO (λ = 2) at 439 K.
Graphical abstractThe selective oxidation of CO has been studied over different Pt/zeolite catalysts. The effect of H2O and CO2 in the reactor depended on the specific catalyst, with the stronger influence for Pt–ETS-10:CO2 strongly inhibited its activity and also caused a large decrease in its selectivity but these effects were completely reversed upon the introduction of water.Figure optionsDownload full-size imageDownload as PowerPoint slide
