Abstract:
In this paper, La2Ce2O7 powders co-activated by Ho3+ and Yb3+ were synthesized by a high temperature solid-state reaction. Both Ho3+ and Yb3+ substitute the La3+ sites in the La2Ce2O7 lattice, where the Ho3+ concentration is 0.5 at.% and the Yb3+ concentration varies in the range of 10~18% at.%. Pumped by a 980 nm laser, the up-conversion (UC) green emission peak at 547 nm and the red emission at 661 nm were detected. When the doping concentration of Ho3+ and Yb3+ are 0.5 at.% and 14% at.%, respectively, the UC emission reaches the strongest intensity. The temperature-sensing performance of La

Abstract:
The properties of supports (such as oxygen vacancies, oxygen species properties, etc.) significantly impact the anti-carbon ability due to their promotional effect on the activation of CO2 in dry reforming of methane (DRM). Herein, pyrochlore-type La2Ce2O7 compounds prepared using co-precipitation (CP), glycine nitrate combustion (GNC) and sol–gel (S-G) methods, which have highly thermal stability and unique oxygen mobility, are applied as supports to prepare Ni-based catalysts for DRM. The effect of the calcining temperature (500, 600 and 700 °C) on La2Ce2O7(CP) has also been investigated. Ba

Abstract:
Due to the susceptible reaction BaCeO3-based proton-conductors toward steam and carbon dioxide, La2Ce2O7(LCO) is proposed as a protect layer on top of solid electrolyte since LCO has shown high proton conductivity with adequate stability against steam. In the study, La(NO3)3·6H₂O and Ce(NO3)3·6H₂O were used as precursors to obtain La2Ce2O7(LCO). Particle size analyzer and XRD are applied to analysis this result. From the XRD analysis, it can be seen at the temperature range above 900°C, the reflections representing fluorite-structured LCO appeared with other reflections from BaCe0.5Zr0.3Y0.2O3

La2Ce2O7 nano-powders with cubic fluorite structure have been firstly prepared by Molten Salts method. These nano-powders were prepared at relatively low temperatures(800°C and 900 °C) at different time, using La(NO3)3•6H2O and La(NO3)3•6H2O as raw materials, as well as K2SO4 (anhydrous) and Na2SO4 (anhydrous) as molten salts and dispersant. XRD, SEM were used to characterize the composition, morphology and size of prepared products. The procedure is facile and suitable for the synthesis of the La2Ce2O7 nano-particles and it will be an excellent method for preparation of other pyrochlore type

Abstract:
Ammonia is one of the promising carriers for hydrogen and a critical ingredient in many industries including fertilizers and pharmaceuticals. In the KAAP process, ruthenium- (Ru-) based catalysts showed 10-20 more activity compared with iron- (Fe-) based catalysts. The modifications that are applied to Ru-based catalysts revolve around changing the material of its support and/or promoters. This study compares the performance of a Ru-based catalyst for ammonia synthesis supported by La2Ce2O7 using barium (Ba), cesium (Cs), potassium (K), and lithium (Li) as promoters.

Abstract La2Ce2O7 (LCO) is one of the promising candidates of high temperature thermal barrier coating materials. However, during plasma spraying, the evaporation of both CeO2 and La2O3 in high temperature plasma jet leads to deviation of coating composition from the starting powder particle. Such change results in significant inhomogeneity of compositions within a coating which influences the performance of resultant coating. In this study, an agglomerated La2Ce2O7 powder with Ce / La ratio of 1.5 and in a size range of 5-60 μm was used to deposit the splats and coatings under different plasm

Abstract:
Abstract LCO (La2Ce2O7), a solid solution of La2O3 in CeO2, is a promising top coating in TBCs. However, it is generally necessary to use LCO as a top coat on YSZ coating to construct a multilayer TBC due to poor mechanical properties of LCO. Therefore, the thermal and chemical stability of LCO/YSZ at high temperature environment become important issue. In this paper, the 50LCO-50YSZ composite coating was deposited using blend powders of YSZ and LCO. The LCO powders used have a nominal particle size range from 10 to 44μm. The LCO/YSZ deposits were exposed at 1300 ¢XC for different durations. T

The mixture of LC and YSZ can effectively eliminate the sudden decrease of thermal expansions coefficients of LC. The results of CMAS corrosion tests indicated that the LC/YSZ composite coating reveals high resistance to the penetration of CMAS with reprecipitation of La-Ce apatite, CaAl2Si2O8, MgAl2O4 and t-ZrO2.

The phase composition and microstructures were studied by XRD and SEM technology. The thermal conductivity and linear thermal expansion coefficient were investigated by laser-flash method and pushing-rod method respectively. XRD results revealed that LZ7C3 is a mixture of pyrochlore and fluorite, and the pyrochlore is the main phase which is a small solid solution of La2Ce2O7 (LC) in La2Zr2O7 (LZ).
