“…In binary CuO/CeO 2 catalysts, a strong catalytic synergy between CuO and CeO 2 has ever been found [7][8][9][10]. However, as far as we know, little attention has been paid to the ternary CuO/Ti x Ce 1-x O 2 catalysts for low-temperature CO oxidation.…”

“…Among them, copper-based catalysts attract special interest due to their low price and greater activity compared to other transition metals like Co, Ni, Cr, and Zn [3,4]. Recent research has demonstrated that highly dispersed CuO on reducible metal oxides such as TiO 2 [5], a-Fe 2 O 3 [6] and CeO 2 [7][8][9][10] has high activity for CO oxidation.…”

“…8 After 0.5 h, 0.2 mol/L NaOH was added gradually until the pH of the mixture was 10 . After further stirring for 12 h, the suspension was aged at 90°C for 3 h, washed with hot water, dried at 80°C for 8 h, then milled and calcined at different temperatures (400, 500, 600, 700 and 800°C, respectively) for 4 h in air.…”

Ternary nanostructured CuO/Ti 0.8 Ce 0.2 O 2 catalysts were prepared by a one-step surfactant-assisted method of nanoparticle assembly. The textural and structural properties of the CuO/Ti 0.8 Ce 0.2 O 2 catalysts were characterized by XRD, TGA, BET, XPS and H 2 -TPR. Their catalytic performance for low-temperature CO oxidation was studied by using a catlab system. CuO supported on binary Ti 0.8 Ce 0.2 O 2 support showed higher catalytic activity than CuO supported on single CeO 2 or TiO 2 support. The calcination temperature had a remarkable influence on the catalytic activity of the CuO/Ti 0.8 Ce 0.2 O 2 catalysts. The CuO/Ti 0.8 Ce 0.2 O 2 catalyst calcined at 500°C exhibited the highest catalytic activity with T 50% and T 100% at 82 and 123°C, respectively. According to the XRD, BET and H 2 -TPR analyses, the higher surface areas and more highly dispersed small particle size CuO should be responsible for the high catalytic activity of catalysts.

Cerium oxide‐doped ZnFe2O4 sorbents supported on modified semi‐coke (MSC) were prepared to improve the desulfurization efficiency of zinc ferrites. The sulfidation tests of the ZnFe2O4/MSC sorbents with and without Ce were carried out using a fixed‐bed reactor at 450 °C. The effect of the CeO2/ZnFe2O4 molar ratio of the sorbents on the sulfur capacity was studied. The characteristics of the sorbents were analyzed by X‐ray diffraction, N2 adsorption, scanning electron microscopy and X‐ray photoelectron spectroscopy. The results showed that cerium oxide could greatly improve the desulfurization reactivity of the ZnFe2O4/MSC sorbents. The molar ratio of Ce to Zn and Fe influences the desulfurization reactivity, and a good sulfur capacity of the sorbent can be obtained with a Ce/Zn/Fe ratio of 4:4:1. It was also found that the addition of CeO2 could enlarge the surface area and the pore volume, thus improving the dispersion of active components. Ce doping results in an increment of the oxygen adsorbed on the sorbent surface, which facilitates the adsorption of H2S. The Ce ions could act as carriers of the oxidation and reduction reactions and the oxygen transfer could be accelerated during the desulfurization process of coal gas.
