Summary: A newly synthesized green-fluorescent, orthorhombic, bromide-rich, perovskite nanocrystal obtained from an unprecedented bromide precursor was found to be an excellent visible-light photocatalyst for the synthesis of gem-dihaloenones. The CsPbBr3 nanocrystal catalyzed the cleavage of CBrX3 followed by cross-coupling with terminal alkynes to produce gem-dihaloenones. These findings not only enrich the synthetic methodology of CsPbBr3 but also inspire the development of efficient and cost-effective photocatalytic materials.

Summary: Recent studies have shown that the emission of free excitons (FE) and self-trapped excitons (STE) can be achieved in two-dimensional hybrid metal halides (HMHs) by adjusting the halogens and organic cations. In this study, pressure-tuned transitions between FE and STE emission were observed in 2D (C7H7N2)(2)PbCl4. On the other hand, only tunable FE emission was observed in 2D (C7H7N2)(2)PbBr4 with a similar structure under compression. This research uncovers the complex interplay among factors such as structure stiffness, Coulomb force, and inorganic octahedral distortion that determines the optical response in 2D HMHs.

Summary: Enthusiasm for the exploration of nonlinear alkali metal borates remains high. In this study, two noncentrosymmetric borates, Li3B8O13Cl and Li3B8O13Br, were successfully obtained using a high-temperature solution method under vacuum conditions. The crystal structures of Li3B8O13X exhibit two independent alternately arranged three-dimensional B-O network structures. Performance measurements show that both materials have short ultraviolet cutoff edges. Theoretical calculation reveals that the BO3 units contribute to their large optical anisotropy with specific birefringence values at 1064 nm.

Summary: The interaction between solid electrolytes and lithium metal is crucial for the performance of all-solid-state Li batteries. Halide superionic conductors have emerged as high-performance solid electrolytes, but their compatibility with lithium metal has not been systematically studied. The presence of electronic conducting components in the interphases formed with lithium metal is detrimental to the compatibility of halide solid electrolytes.

Summary: Perovskite light-emitting diodes (PeLEDs) based on 3D mixed Br-Cl compositions exhibit good color stability and efficiency in the sky-blue range, but suffer from a significant performance decay in the deep-blue emission. This decay is mainly attributed to the poor morphology of the emissive layer. By combining theoretical and experimental approaches, it is discovered that the exchange of halide ions in lead complexes drives the precipitation of CsCl, resulting in low solubility at high Cl/Br ratios and inadequate perovskite film coverage. A metastable dissolution strategy is proposed, leading to deep-blue PeLEDs with a record high EQE of 4% and excellent spectral stability.

Summary: This study successfully controlled the sp3 defect density in metal-free carbon catalysts by constructing a core-shell structure with a rigid shell on the surface of polymeric precursor microspheres. The sp3 defects were effectively controlled by varying the thickness of the shell. Increasing the sp3 defect density significantly enhanced the oxygen reduction reaction (ORR) activity of the carbon catalysts. Theoretical calculations revealed that synergizing with graphitic-N can enhance the intrinsic ORR activity of sp3 defects. Therefore, the strategy of confined space modulation is a promising approach for controlling the sp3 defect density in organics-derived carbon-based catalysts.

Summary: Interface engineering is a promising strategy to enhance the catalytic performance of electrocatalysts for the oxygen reduction reaction (ORR). The study prepared a model catalyst (FeCu@NC) loaded with nanocluster-scaled Fe2O3/Cu interfaces and demonstrated their superior ORR activity and zinc-air battery performance. It was found that the presence of the Fe2O3/Cu interface breaks the traditional cognition and gives Cu atoms a slight positive charge, serving as active sites for the ORR.

Summary: Metal-organic frameworks (MOFs) have been used as precursors for carbon-based electrocatalysts. This study investigates the influence of MOF type on the structure and ORR activity of metal-free carbon catalysts derived from them. It is found that the coordination environment of Zn in MOFs and its reactivity with urea play a decisive role in the doped N and morphology of the derived carbon catalysts. Despite different structures and porosities, carbon catalysts derived from different MOFs exhibit superior ORR activity and Zn-air battery performance. The combination of urea and compounded Zn shows promise as an activation method for efficient metal-free carbon electrocatalysts.

Summary: The embedding of metal nanoparticles in metal-organic frameworks (MOFs) is crucial in catalysis research, as it prevents agglomeration and allows for functionalization of the MOF matrix to optimize the chemical environment. In this study, Pd nanoparticles were incorporated into the MOF CuBTC by encapsulation, and the hydrophobicity was adjusted by using functionalized linkers. These modifications significantly improved the catalytic activity, suggesting that channel engineering is an efficient way to optimize metal@MOF catalysts.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.
