Summary: The effects of La3+ and Al3+ substitution on the structural, dielectric, and piezo-electric properties of (1-x)(K0.5Bi0.5)TiO3-xLaAlO3 ceramics were investigated. With the increase in LAO content, a decrement in tetragonal distortion and an increase in cubic symmetry were observed. The incorporation of LAO in KBT resulted in an improved relaxor behavior and a suppression of oxygen vacancies. The piezo-electric properties were enhanced, with the 3% LAO-doped sample exhibiting the highest piezo-electric charge coefficient and improved piezo-electric voltage coefficient. An energy harvesting experiment was performed on the poled 3% LAO-doped ceramic, showing promising results under normal finger tapping.

Summary: We have discovered a facet-assisted mechanism for separating photocarriers in flux-treated Bi4TaO8Cl crystals with {001} and {110} facets. These facets have different energy states that generate an internal electric field to direct photocarriers to different facets. By selectively depositing CoOx cocatalyst on the {001} facets, we enhance interfacial charge transfer reactions. This facet engineering enables controlled flow of photocarriers from the bulk to the surface for catalytic reactions, achieving unprecedented high quantum efficiency and stable water splitting.

Summary: Narrow-bandgap perovskite oxynitrides show promise as inorganic photocatalysts for solar energy conversion. However, conventional synthetic methods lead to high defect concentrations, particularly at grain boundaries, which negatively impact photocatalytic performance. This study demonstrates that defect-free LaWO0.6N2.4 single crystals can be produced by the topotactic conversion of BiLaWO6, and these crystals exhibit good photocatalytic activity for water oxidation. They achieved an apparent quantum efficiency of 0.13% at 800 ± 20 nm, the highest reported for near-infrared-light active oxynitrides. The crystals also enabled steady overall water splitting under visible light illumination. These findings highlight the potential of porous single crystals as a platform for enhancing the performance of oxynitride photocatalysts and the importance of W-based perovskite oxynitrides for solar energy conversion.
