In this study, Ce0.65Zr0.25RE0.1O2−δ (RE = Tb, Gd, Eu, Sm, Nd, Pr, and La) solid solutions were successfully prepared by the glycine-nitrate process tested for CO oxidation activity. The X-ray diffraction results confirmed formation of complete solutions. Raman spectroscopy measurements suggested presence oxygen vacancies due to defective structure further evidenced solution. high-resolution transmission electron microscopy observations showed nanocrystalline nature From photoelectron...
Low temperature CO oxidation reaction is known to be facilitated over platinum supported on a reducible cerium oxide. Pt species act as binding sites for reactant molecules, and oxygen vacancies surface of oxide atomically activate the O2 molecules. However, impacts size concentration vacancy at have not been clearly distinguished, thereby various diverse approaches suggested date. Here using co-precipitation method we prepared pure ceria support infiltrated it with solution obtain 0.5...
The overpotentials of the oxygen reduction on perovskite oxide catalysts were significantly reduced simply by mixing catalyst particles with polypyrrole/carbon composites (pPy/C).
Voltage control of interfacial magnetism has been greatly highlighted in spintronics research for many years, as it might enable ultra-low power technologies. Among few suggested approaches, magneto-ionic demonstrated large modulation magnetic anisotropy. Moreover, the recent demonstration devices using hydrogen ions presented relatively fast magnetization toggle switching, tsw ~ 100 ms, at room temperature. However, operation speed may need to be significantly improved used modern...
Ammonia is a promising carbon-free hydrogen carrier. Owing to their nickel-rich anodes and high operating temperatures, solid oxide fuel cells (SOFCs) can directly utilize NH
Single-atom Pt/ceria catalysts are extremely active and thermally stable at over 700 °C in high-temperature solid oxide cell electrodes.
Steel slag powder (SS), ground granulated blast-furnace (GGBS), and flue gas desulfurization gypsum (FDG) are environmentally friendly cost-effective substitute materials for ordinary Portland cement (OPC). This study investigated the use of industrial solid wastes, including SS, GGBS, FDG, as auxiliary in OPC to stabilize pretreated recycled concrete aggregate (pretreated RCA). The RCA, mixed cementitious materials, water at optimum content created a mixture designated cement-stabilized...
In order to reuse granulated blast furnace slag (GBFS) and low-strength soft clay (SC), this study developed a curing material using magnesium oxide (MgO) as an alkali activator excite the GBFS basalt fiber (BF) reinforcing prepare SC. The mixing ranges of GBFS, MgO, BF were established 9.48%~14.52%, 0.48%~5.52%, 0%~1.00454% dry mass, respectively, ratios three optimized central composite design (CCD) test. Through analysis variance, factor interaction analysis, parameter optimization CCD...
The nano-size effect, which indicates a drastic increase in conductivity solid electrolyte materials of nano-scale microstructures, has drawn substantial attention various research fields including the field oxide fuel cells (SOFCs). However, especially cases ultra-thin films measured an in-plane configuration, it is highly possible that 'apparent' originates from electrical current flowing through other conduction paths than thin film. As systematic study to interrogate those measurement...
We demonstrate a highly reliable diffusion-blocking layer that suppresses detrimental chemical interactions at elevated temperatures.
A strategy of naturally diffused sintering aid enables the fabrication defect-free bilayer electrolyte in solid oxide cells.
