Summary: Researchers successfully constructed an integrated photoanode by modifying BiVO4 with In2O3 layer and further decorating amorphous FeNi hydroxides, improving its performance significantly. The BV/In/FeNi photoanode showed a remarkable increase in photocurrent density and water oxidation reaction kinetics. This improvement was attributed to the formation of BV/In heterojunction inhibiting charge recombination and the decoration of FeNi facilitating the water oxidation reaction kinetics and hole transfer.

Summary: In this study, conductive substrates of Ti3C2 and TiO2/Ti3C2 were prepared and utilized for the in-situ growth of hematite via electrophoretic deposition and hydrothermal methods. The TiO2/Ti3C2-hematite photoanode exhibited a significantly enhanced photocurrent density of 1.29 mA cm-2, which was 3.7 times higher than that of the FTO-hematite. This improvement was attributed to the improved interface property and the larger specific surface area provided by the layered TiO2/Ti3C2 conductive substrate.

Summary: In this study, a non-conjugated polymer functional layer (poly(-diallyl-dimethylammonium chloride, PDDA) was introduced between the interfaces of the p-n junction (Co3O4/Gd-Fe2O3) to tune the interfacial properties, which profoundly affects the photoelectrochemical (PEC) water oxidation performance. The PDDA modulates the band structure, passivates the surface trap, and improves the PEC water oxidation kinetics, thereby enhancing the PEC water oxidation performance of the p-n junction.

Summary: This study investigated the electronic properties and structural stability of Nb-doped LaFeO3 oxide, as well as the adsorption of H-2 molecule on both clean and Nb-doped LFO surfaces through theoretical calculations. The results showed that Nb doping improved electrical conductivity and enhanced structural stability of orthorhombic LFO, providing a theoretical explanation for experimental observations. Additionally, Nb doping slightly enhanced the adsorption of H-2 molecule and facilitated the dissociation of H-2 to H atoms.

Summary: This study evaluates the electrochemical performance of SCT10 cathodes in the presence of Cr impurities. The results demonstrate that Cr impurities lead to significant performance degradation, especially in wet conditions. Morphological damages and the formation of SrCrO4 and Co3O4 secondary phases on the cathode surface contribute to the deterioration of oxygen reduction kinetics and cathode activity. The study highlights the importance of surface Sr segregation in Cr deposition and emphasizes the need for attention in practical applications in solid oxide fuel cells.
