Based on the experimental data and phase compositions, the phase diagram of the CaO-SiO 2 -CeO 2 -10.0wt.% Al 2 O 3 -5.0wt.% MgO system was constructed at 1300°C and 1400°C. There were great discrepancies between the experimental results and calculated results by FactSage 8.2. The ...
FIG. 1 depicts an atomic layer deposition system for fabricating a single dielectric layer formed as a nanolaminate layered sequence of cerium oxide (CeO2) and aluminum oxide (Al2O3), according to various embodiments of the present invention; FIG. 2 illustrates a flow diagram of elements for...
更重要的是,此类催化体系(如 Cu-CeO 2 )是具有较高的电子 - 离子混合导电能力的混合 型导体,且 CeO 2 易于存储、传输氧,可以协助 O 2 从电解质向阳极传递,将阳极氧化反应面扩大至 TPB 面以外,减小界 面阻力,加快氧化反应速率。此特性使其在以甲烷为燃料的固体电解质燃料电池阳极开发领域成为一种值得关注的...

Figure 1.Schematic diagram of the device for thermocatalytic decomposition. 3. Results and Discussion 3.1. Thermal Catalytic Decomposition of DMMP by CuO-CeO2/γ-Al2O3 Figure 2shows the DMMP conversion of CuO/γ-Al2O3and CuO-CeO2/γ-Al2O3as a function of the reaction time. The protecti...
Previously, microwave sintered zirconia based ceramics, such as CeO2 stabilized ZrO2 and Al2O3 reinforced ZrO2, were investigated. Among those ceria + 8 mol % YSZ is considered as a candidate material for thermal barrier coatings. Ceria + 8 mol % YSZ has superior toughness and thermal shock ...
It can be observed that the surfaces of the samples were all covered by white flaky corrosion products or bright corrosion particles, which were presumed to be Al2O3, Al(OH)3 and Mg(OH)2 particles when using the EDS energy spectrum analysis and the characteristic peaks in the XRD patterns...
However, copper is the most important promoter of hydrogen production on inert supports such as Al2O3, La2O3, SiO2, or ZrO2 [12,13,14], leading to high catalytic activity and good selectivity and yield to H2 [12,13,15,16]. This is attributed to copper acting as an active agent: ...
