Title: Novel manganese-promoted inverse CeO₂/CuO catalyst: In situ characterization and activity for the water-gas shift reaction

Abstract

In this study, the behavior of a novel manganese-promoted inverse CeO₂/CuO catalyst under water-gas shift (WGS) reaction conditions is studied. CeO₂/CuO and CeO₂/Mn-CuO catalysts are characterized by X-ray diffraction (XRD), Raman and X-ray photoelectron spectroscopy (XPS). Structure/activity relationships and redox characteristics are established on the basis of such results along with those of in situ XRD and X-ray absorption fine structure (XAFS) experiments performed either under WGS or CO-temperature programmed reduction (TPR) conditions. The manganese coprecipitated together with the copper during the preparation of the samples and the Mn-CuO phase strongly affected the size and chemical properties of the catalytically-active ceria nanoparticles. A manganese-induced enhancement on the WGS activity was observed. As a result, differences in the characteristics of the supported ceria particles are proposed as most relevant to explain the observed Mn-promoting effect.

Importance of Low Dimensional CeO _x Nanostructures in Pt/CeO _x –TiO ₂ Catalysts for the Water–Gas Shift Reaction

Journal Article Luo, Si ; Barrio, Laura ; Nguyen-Phan, Thuy-Duong ; ... - Journal of Physical Chemistry. C

CO₂ and H₂ production from the water–gas shift (WGS) reaction was studied over Pt/CeO_x–TiO₂ catalysts with incremental loadings of CeO_x, which adopts variations in the local morphology. The lowest loading of CeO_x (1 wt % to 0.5 at. %) that is configured in its smallest dimensions exhibited the best WGS activity over larger dimensional structures. We attribute this to several factors including the ultrafine dispersed one-dimensional nanocluster geometry, a large concentration of Ce³⁺ and enhanced reducibility of the low loadings. We utilized several in situ experiments to monitor the active state of the catalyst during the WGS reaction. X-ray diffractionmore »« less

Pulse studies to decipher the role of surface morphology in CuO/CeO₂ nanocatalysts for the water gas shift reaction

Journal Article Rodriguez, Jose A. ; Zhao, Fuzhen ; Liu, Zongyuan ; ... - Catalysis Letters

The water-gas shift reaction (WGS, CO + H₂O → CO₂) was studied over CuO/CeO₂ catalysts with two different ceria particle morphohologies, in the form of nanospheres (ns) and nanocubes (nc). To understand the strong dependence of the WGS reaction activity on the ceria nanoshapes, pulses of CO (without and with water vapor) were employed during in situ X-ray diffraction (XRD) and X-ray absoprtion near edge structure (XANES) measurements done to characterize the catalysts. The results showed that CuO/CeO₂ (ns) exhibited a substantially better activity than CuO/CeO₂ (nc). The higher activity was associated with the unique properties of CuO/CeO₂ (ns), suchmore »« less

Structural and Chemical Evolution of an Inverse CeO_x/Cu Catalyst under CO₂ Hydrogenation: Tunning Oxide Morphology to Improve Activity and Selectivity

Journal Article Moncada, Jorge ; Chen, Xiaobo ; Deng, Kaixi ; ... - ACS Catalysis

Small nanoparticles of ceria deposited on a powder of CuO display a very high selectivity for the production of methanol via CO₂ hydrogenation. CeO₂/CuO catalysts with ceria loadings of 5%, 20%, and 50% were investigated. Among these, the system with 5% CeO_x showed the best catalytic performance at temperatures between 200 and 350 °C. The evolution of this system under reaction conditions was studied using a combination of environmental transmission electron microscopy (E-TEM), in situ X-ray absorption spectroscopy (XAS), and time-resolved X-ray diffraction (TR-XRD). For 5% CeO_x/Cu, the in situ studies pointed to a full conversion of CuO into metallicmore »« less

Origin of Active Oxygen in a Ternary CuO_x /Co₃O₄–CeO ₂ Catalyst for CO Oxidation

Journal Article Liu, Zhigang ; Wu, Zili ; Peng, Xihong ; ... - Journal of Physical Chemistry. C

In this paper, we have studied CO oxidation over a ternary CuO_x/Co₃O₄-CeO₂ catalyst and employed the techniques of N₂ adsorption/desporption, XRD, TPR, TEM, in situ DRIFTS and QMS (Quadrupole mass spectrometer) to explore the origin of active oxygen. DRIFTS-QMS results with labeled 18O2 indicate that the origin of active oxygens in CuO_x/Co₃O₄-CeO₂ obeys a model, called as queue mechanism. Namely gas-phase molecular oxygens are dissociated to atomic oxygens and then incorporate in oxygen vacancies located at the interface of Co₃O₄-CeO₂ to form active crystalline oxygens, and these active oxygens diffuse to the CO-Cu⁺ sites thanks to the oxygen vacancy concentrationmore »« less

Effect of redox promoters (CeO_x and CuO_x) and surface sulfates on the selective catalytic reduction (SCR) of NO with NH₃ by supported V₂O₅-WO₃/TiO₂ catalysts

Journal Article Guo, Mingyu ; Mosevitzky Lis, Bar ; Ford, Michael E. ; ... - Applied Catalysis. B, Environmental

A series of TiO₂-supported MO_x catalysts (M=V, W, Ce, Cu and S) were investigated for their SCR activity. In situ Raman spectroscopy indicated that the supported MO_x phases were completely dispersed as surface sites on the TiO₂ support. In situ IR revealed that surface VO_x, WO_x and SO_x sites anchored at both CeO_x/CuO_x and TiO₂ sites. The number of surface Lewis acid sites decreased with the addition of basic (CeO_x/CuO_x) and acidic (VO_x/WO_x) sites in all catalysts, and acidic SO_x in the unpromoted and Ce-promoted catalysts. The surface VO_x, WO_x and SO_x sites introduced surface Brønsted acid sites. The redoxmore »« less
