Summary: The structural evolution, electrical conductivity, oxygen nonstoichiometry, and oxygen transport properties of La1-xCaxFeO3-δ perovskite-type oxides were investigated. The results showed that Ca doping is mainly compensated by formation of electron holes rather than by oxygen vacancies, and oxygen vacancy diffusion coefficient and ionic conductivity increase with increasing Ca content in the compositions. The effective migration barrier for oxygen diffusion decreases with decreasing oxygen vacancy formation enthalpy.

Summary: The effect of Co doping on the phase structure and oxygen permeability of BaFeO3-delta hexagonal composite was investigated. It was found that the introduction of Co can transform hexagonal BaFeO3-delta into a cubic perovskite structure. The substitution of Fe with Co in the range of 10-50% can stabilize the pure cubic perovskite structure even at room temperature. Increasing the cobalt doping content improves the lattice volume and oxygen permeability of BaCoxFe1-xO3-delta (x=0.1-0.5) through structural optimization. Among the BaCoxFe1-xO3-delta (x=0.1-0.5) samples, BaCo0.4Fe0.6O3-delta exhibits excellent oxygen permeability and structural stability due to its optimal Gold Schmidt tolerance factor. However, BaCo0.5Fe0.5O3-delta shows the highest oxygen permeation flux at elevated temperatures but poor oxygen permeability below 750 degrees C due to structural phase transition. This study provides insights into the optimal range of Co doping to stabilize the cubic perovskite structure in BaCoxFe1-xO3-delta.

Summary: To enhance the electrocatalytic activity and stability of LSCF oxygen electrodes in RSOCs, a Pd-LSCF composite oxygen electrode was prepared using a conventional physical mixed method. The Pd-LSCF|GDC|YSZ|Ni-YSZ cell exhibited excellent electrochemical performance in both SOFC and SOEC modes. The power density of the cell in the SOFC mode reached 1.73 W/cm(2) at 800 degrees C, higher than that of the LSCF oxygen electrode. In the SOEC mode, the current density at 1.5 V was 1.67 A/cm(2) at 800 degrees C under 50 vol% steam concentration. The long-term reversible operation of the RSOCs showed a low degradation rate of 2.2%/100 h and 2.5%/100 h in the SOEC and SOFC modes, respectively. These findings demonstrate that the incorporation of Pd into LSCF electrode significantly improves its electrochemical performance in RSOCs.

Summary: Composite ceramic membranes based on BTM and LSM exhibit high oxygen flux values, with the oxygen permeability becoming more bulk-limited as the temperature increases. The oxygen exchange coefficients of BTM-LSM are significantly higher than its constituent phases, and introducing electronic conductivity into BTM increases the surface exchange coefficients. However, the oxygen flux of BTP remains lower compared to percolating BTM-LSM composites.

Summary: We demonstrate a composite photocatalyst for nitric oxide conversion with a Cu-Fe alloy, graphitic carbon nitride (g-C3N4), and ZnIn2S4. The superior photocatalytic performance of 6.45-fold that of g-C3N4 was confirmed. The delay effect on charge recombination was observed through time-resolved photoluminescence, and heterojunction establishment was attributed to the hole-trapping ability of ZnIn2S4. The combined effects of the Cu-Fe alloy were confirmed by NO-specific adsorption and conversion experiments, and the active species involved were examined via electron spin resonance. Density functional theory calculations revealed the molecular mechanisms of photocatalytic conversion of NO to NO3-. Therefore, g-C3N4|ZnIn2S4|CuFe has potential for sustainable and efficient pollutant conversion.

Summary: Metal-air batteries generate electrical energy by combining metal and oxygen, and they are considered a promising technology due to their high energy density, low cost, and environmental friendliness. However, the difficulties in decomposing the discharge products result in a high overpotential. Recent research has shown that semiconductors can capture solar energy and improve the battery reaction by increasing electron migration rate. This review paper discusses the fundamentals of photoelectrochemistry, photocathode design principles, various photocatalysts, challenges caused by light, and perspectives for the development of high-performance light-assisted metal-air batteries.

Summary: In this study, a La0.8Ca0.2Fe0.94O3-6-0.05Ag (LCF-Ag) hollow fiber membrane with three-layer sandwich structure was successfully prepared. The oxygen permeation flux of the membrane structure was 1.79 times higher than that of the traditional membrane structure, with a maximum oxygen flux of 2.15 mL min-1 cm-2. The membrane showed high stability during a 240-hour long-term operation, and the oxygen flux could be fully recovered by switching the sweep gas to He, indicating its good chemical stability. These results demonstrate the feasibility of the new membrane structure for oxygen separation with CO2 resistance.

Summary: The development of materials with high intrinsic activity for oxygen activation and bulk proton conductivity is crucial in protonic ceramic fuel cells. However, a higher water content, while beneficial for increasing proton conductivity, can dilute oxygen and suppress oxygen adsorption on the electrode surface. To overcome this dilemma, a new electrode design concept is proposed, which involves introducing a second phase with high-hydrating capability into a conventional cobalt-free perovskite to form a unique nanocomposite electrode. This design enables high proton conductivity and concentration at low water content, and the hydronation also creates additional fast proton transport channels along the two-phase interface.
