N2O decomposition over CuO/CeO2 catalyst: New insights into reaction mechanism and inhibiting action of H2O and NO by operando techniques

In this work, a combination of ex situ (STEM-EELS, STEM-EDX, H2-TPR and XPS), in situ (CO-DRIFTS) and operando (DR UV?vis and DRIFTS) approaches was used to probe the active sites and determine the mechanism of N2O decomposition over highly active 4?wt.% Cu/CeO2 catalyst. In addition, reaction pathways of catalyst deactivation in the presence of NO and H2O were identified. The results of operando DR UV?vis spectroscopic tests suggest that [Cu?O?Cu]2+ sites play a crucial role in catalytic N2O decomposition pathway. Due to exposure of {1?0?0} and {1?1?0} high-energy surface planes, nanorod-shaped CeO2 support simultaneously exhibits enhancement of CuO/CeO2 redox properties through the presence of Ce3+/Ce4+ redox pair. Its dominant role of binuclear Cu+ site regeneration through the recombination and desorption of molecular oxygen is accompanied by its minor active participation in direct N2O decomposition. NO and H2O have completely different inhibiting action on the N2O decomposition reaction. Water molecules strongly and dissociatively bind to oxygen vacancy sites of CeO2 and block further oxygen transfer as well as regeneration of catalyst active sites. On the other hand, the effect of NO is expressed through competitive oxidation to NO2, which consumes labile oxygen from CeO2 and decelerates [Cu+ Cu+] active site regeneration.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: Cu2O, you can also check out more blogs aboutHPLC of Formula: Cu2O

Effect of surface treatment of the support on co oxidation over carbon-supported Wacker-type catalysts

The impact of surface treatment of the support on the oxidation of CO over carbon-supported Wacker-type catalyts was studied. This study focused on the effect of the chemical properties of activated carbon on CO oxidation over supported PdCl2-CuCl2 and PdCl2-CuCl2-Cu(NO)32 catalyts. The surface of active carbon used to prepare supported Wacker-type catalysts was enriched with carboxylic acid and carbonyl groups by pretreating with HNO3 or adding Cu(NO3)2 as a supplementary copper precursor. These surface groups improved the hydrophilicity and facilitated the formation of an active copper phase (Cu2Cl(OH)3). The effects were stronger, particularly on the formation of Cu2Cl(OH)3, when Cu(NO3)2 was combined with CuCl2 as catalyst precursors. The acceleration of CO oxidation can be attributed to the formation of the active copper phase and the improved hydrophilicity.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Related Products of 1317-39-1, you can also check out more blogs aboutRelated Products of 1317-39-1
