Summary: This research presents the spatially confined assembly of semimetallic oxy-anions within P8W48, resulting in the formation of three crystalline compounds. The structure and composition of these compounds were systematically characterized using various physicochemical techniques. The incorporation of the largest AsIII-oxo cluster in polyoxometalates (POMs) to date and the customization of SbO33- groups in Sb4 and Sb8 were successfully achieved. The encapsulation of semimetallic oxyanions within P8W48 provides a valid strategy for the development of host-guest assemblies in POM chemistry, with potential applications in proton-conducting materials.

Summary: Tunable CuxO (core-shell structured Cu2O@CuO and CuO) nanoparticles are loaded on carbon nitride nanotubes using a simple method involving annealing under different atmospheres. The resulting core-shell nanostructures exhibit enhanced photocatalytic nitrogen fixation and quantum efficiency. Compared to other structures, these nanoparticles also show accelerated charge carrier transfer and increased photoreduction capability.

Summary: A new nanocomposite, synthesized through the sol-gel method, was used as an efficient heterogeneous catalyst in the water oxidation reaction. The nanocatalyst exhibited the highest turnover number, turnover frequency, and O2 evolution at pH=9. The effects of CAN concentration, pH, and KOH amount on the catalytic activity were investigated, and a plausible reaction mechanism was proposed.

Summary: Solid-state halide electrolytes with high ionic conductivity were successfully synthesized using ammonium-assisted wet chemistry. Microstrain-induced microstructure changes were found beneficial for lithium ion transport. Alleviating interfacial incompatibility between halide electrolytes and lithium metal by transforming the interface led to the development of high-performance all-solid-state lithium-metal batteries.

Summary: This study presents a new solid-state approach for synthesizing phthalocyanines, reducing the amount of the flammable and harmful solvent DMAE. Through systematic screening of reaction parameters, the influence of temperature, presence of a template, and the role of DMAE in the conversion of phthalonitrile to phthalocyanine was revealed. These results lay the foundations for greener synthesis of high-performance dyes and expand the application of solid-state synthesis to a wider family of phthalocyanines.

Summary: Solid electrolytes are crucial for the safety, reliability, and performance of all-solid-state lithium batteries. Argyrodites, as a relatively new class of solid electrolytes based on sulfides, show high ionic conductivity, low cost, and good compatibility with Li metal, but still face challenges in practical applications despite continuous research improvements.

Summary: The low conductivities of ions and electrons in the cathode, as well as poor cathode interface performance, are major challenges in the application of garnet solid-state batteries. This study proposes the use of a single-phase garnet-type mixed ionic and electronic conductor (MIEC) as the cathode framework, aiming to achieve high activity and stability at the cathode interface. Through calculations and sintering techniques, a series of garnet-type MIECs have been synthesized and screened, with Li43Fe3La24Zr12Ta4O96 (3Fe) exhibiting excellent electronic conductivity of 2.87 x 10-4 S cm-1 and ionic conductivity of 4.57 x 10-5 S cm-1. This work provides a new strategy to address the cathode interface problem in garnet solid-state batteries.

Summary: The rational solid-state synthesis of inorganic compounds involves catalytic nucleation on crystalline reactants, where contributions of reaction and interfacial energies to nucleation barriers are approximated from thermo-chemical data and crystal features. Favorable synthesis reactions are identified by Pareto analysis of relative nucleation barriers and phase selectivities, enabling reaction planning for a range of compounds and discussing pathways for retrosynthesis of inorganics.

Summary: Since the breakthrough in 2018, research on halide solid-state electrolytes (SSEs) has gained momentum. Halide SSEs have more balanced properties compared to oxide and sulfide SSEs, making them suitable for all-solid-state batteries (ASSBs). This article provides a comprehensive overview of halide SSEs, including screening principles, structural design theories, substitution strategies, moisture resistance mechanisms, synthesis methods, and application prospects in ASSBs.

Summary: Garnet-type Ta-substituted Li7La3Zr2O12 materials have attracted attention as solid electrolytes for future oxide-based all-solid-state lithium-ion batteries due to their superior ionic conductivity and stabilities. However, high-temperature sintering needed for high lithium-ion conductivity leads to the formation of insulating interface impurities. In this study, low-temperature sintering of submicrometer-sized garnet-type LLZT fine powder at 400 degrees C was demonstrated, achieving high lithium-ion conductivity without interface impurities.
