Summary: This study successfully fabricated well-aligned WO3 snowflake-like hierarchical arrays with (020) facet perpendicular to the FTO substrate. The fabricated samples were characterized by XRD, SEM, and UV-vis. The SHA photoanode exhibited an impressive photocurrent density of 2.43 mA·cm^-2 at 1.23 V vs RHE, which is 1.76 times higher than the sandwich-like structures. This improved performance can be attributed to the special SHAs and the preferred orientation, which would effectively promote the separation and transfer of carriers.

Summary: In this study, a series of Pr6O11 catalysts were developed by CTAB-assisted coprecipitation method and their catalytic performances for soot oxidation and NOx adsorption were investigated. The Pr6O11 catalysts exhibited excellent catalytic activities for both soot oxidation and NOx adsorption at low temperature, which was attributed to their relatively large surface area, strong NO oxidation ability, and high intrinsic activity. The presence of NO was found to promote the soot oxidation, and the possible mechanism of the soot oxidation reaction process was explored using in situ DRIFTS.

Summary: Mixed transition metal oxides are promising electrode materials for electrochemical energy storage and conversion. The synthesis of these materials with tailored composition, crystal structure, and morphology is crucial for optimizing their properties. This study reports on the room-temperature electrodeposition of a ternary oxide, ZnMnO3, using earth-abundant metals. The epitaxial growth of ZnMnO3 on ZnO nanowires results in a 2-dimensional morphology and shows promise for the direct growth of other mixed transition metal oxides on conductive substrates.

Summary: We predict and realize a new magnetic and semiconducting material, MnSnN2, through combinatorial sputtering of thin films. MnSnN2 exhibits a wide composition tolerance, with a single-phase region of 20% < Mn/(Mn + Sn) < 65%. The material shows a wurtzite-like crystal structure with cation disorder and has an optical absorption onset of 1 eV, consistent with the computationally predicted 1.2 eV bandgap. Resistivity and Hall effect measurements confirm the semiconducting nature of MnSnN2 and reveal complex charge transport mechanisms. Magnetic susceptibility measurements show a low-temperature magnetic ordering transition and strong antiferromagnetic correlations in MnSnN2, contrasting with previous studies on cation-ordered MnSiN2 and MnGeN2.
