Optimal Ru particle size for selective CO oxidation in H2 over Ru/κ-Al2O3
Park JE, Park ED
Ru/κ-Al2O3 catalysts with different Ru dispersions were prepared by controlling the pretreatment conditions, and were applied to selective CO oxidation in H2. The prepared catalysts were characterized by N2 physisorption, transmission electron microscopy, temperature-programmed oxidation, CO chemisorption, and O2 chemisorption. The Ru dispersion decreased with increasing reduction and oxidation temperature of Ru/κ-Al2O3. The turnover frequency for CO oxidation in H2 increased as the Ru particle size increased from 2.2 to 3.6 nm, whereas the apparent activation energy decreased as the Ru particle size increased from 2.2 to 3.4 nm for 1% Ru/κ-Al2O3. However, larger Ru particles were not always favorable for the selective CO oxidation in H2 because H2 oxidation was also promoted by these catalysts. In the case of the 1 wt% Ru/κ-Al2O3 catalyst, Ru nanoparticles of approximately 3 nm appeared to be optimal for the selective CO oxidation in H2 on the basis that they provided the widest temperature window, resulting in complete removal of CO even in the presence of H2O and CO2.
