The Influence of Support on the Low-Temperature Activity of Pd in the Reaction of CO Oxidation

Low-temperature oxidation of CO over Pd/CeO2–TiO2 catalysts with different pretreatments

“…However, the DRIFTS indicated that CO adsorption on Pd/TiO 2 is weak at ambient temperature, especially after the reduction pretreatment. Therefore, CO oxidation over Pd/TiO 2 then takes place between the weakly adsorbed CO and oxygen on metallic Pd sites through the LH mechanism, which is in agreement with the mechanisms proposed by Kochubey and Pavlova et al [55][56][57].…”

Hydrocarbon specificity in the selective catalytic reduction of NOx over Cu-ZSM-5 and Co-ZSM-5 catalysts

“…EXAFS spectra were obtained at the EXAFS Station of the Siberian Center of Synchrotron Radiation using vacuum-tight cells [8]. EXCURVE-92 program was used for data analysis.…”

Pd/CeO2?TiO2 catalyst for CO oxidation at low temperature: a TPR study with H2 and CO as reducing agents

“…Catalysts containing noble metals such as Au [1][2][3][4][5][6], Pt [7,8], and Pd [9][10][11][12] have been proved very effective for CO oxidation at low temperature. Pd supported catalysts have drawn much attention due to the excellent activity for the low-tivity for CO oxidation even at relatively low temperatures due to the synergistic effect between gold and TiO 2 support [18].…”

“…Pd supported catalysts have drawn much attention due to the excellent activity for the low-tivity for CO oxidation even at relatively low temperatures due to the synergistic effect between gold and TiO 2 support [18]. Kochubey et al [9] and Pavlova et al [10,11] reported that the CO oxidation at room temperature over Pd supported on TiO 2 , SiO 2 , and γ -Al 2 O 3 was structure-sensitive and proceeded via the interaction between weakly bounded CO and oxygen located at the defect centers [9][10][11].…”
