Summary: AgCl crystals with various morphologies were controllably prepared through a one-pot synthesis method using ethylene glycol as a solvent and AgNO3 as a precursor. The ionic liquid PDDA acted as a Cl- ion precursor and morphology-controlled stabilizer. The effects of temperature, ligand and precursor concentration on crystal growth were investigated, showing different morphological transformations with varying Cl- concentrations. The study provides insights into the growth mechanism of AgCl microcrystals and a new method for synthesizing AgCl crystals with tunable shapes.

Summary: Solar-driven photoelectrochemical (PEC) water splitting relies on efficient and stable photoanodes for the water oxidation reaction. Here, three-dimensional interconnected nanoporous Ta3N5 film photoanodes with controlled thickness were successfully fabricated, showing the highest PEC performance at 900 nm thickness. Electrochemical oxidation at high anodic potentials resulted in severe performance degradation, which could be partially recovered by NH3 re-treatment, while anchoring a dual-layer Co(OH)(x)/CoOOH co-catalyst shell significantly enhanced PEC performance and stability.

Summary: Plate-like perovskite CaMnO3 microcrystals with an average size of -21.89 mu m and a thickness of -3.18 mu m were successfully synthesized through topochemical microcrystal conversion reaction using layer-structured Ca3Mn2O7 pre-cursors. The stability of the perovskite phase was provided by the [MnO6] octahedrons and CaO layer. These plate-like microcrystals can serve as an excellent template for textured CaMnO3-based ceramics through template grain growth.

Summary: A rational and versatile design strategy is proposed to boost the pH-universal HER activity of Ru clusters by exploring supports with both high work function and facilitated water dissociation ability. Heterostructured Mo2C nanoparticles-Ru clusters anchored carbon spheres (Mo2C-Ru/C) are designed and prepared guided by theoretical calculations. Mo2C-Ru/C exhibits low overpotential and small Tafel slope in alkaline solution, as well as excellent activity in alkaline seawater, acidic, and neutral solutions. Mo2C-Ru/C also shows high discharge power density and excellent stability for simultaneous generation of electricity and hydrogen (H-2) in an alkaline-acid Zn-H2O battery.

Summary: Layered double hydroxides (LDHs) have large specific surface areas and rich metal redox sites, making them potentially suitable oxygen evolution reaction catalysts. However, they often exhibit poor hydrogen evolution reaction (HER) activity due to limited conductivity and active sites. In this study, a plasma engraving strategy was developed to enhance the HER activity of NiFe LDH. The plasma engraving process improved the conductivity and active sites by reducing Ni2+ to Ni nanoparticles, generating more oxygen vacancies, and exfoliating nanosheets into thinner ones. The plasma-engraved NiFe LDH (PEH) showed enhanced HER activity with low overpotential and small Tafel slope, outperforming regular NiFe LDH. Furthermore, PEH also displayed excellent HER activity in alkaline real seawater and overall water splitting.

Summary: The hydrogen evolution reaction (HER) has so far been studied mainly in strong acidic/alkaline electrolytes. However, conducting the HER in extreme conditions has proven to have several drawbacks such as electrolyzer corrosion, water pollution, and the use of expensive membranes. Conducting the HER in neutral media is a desirable solution to these issues but faces the challenge of slow kinetics. In this study, a plasma-assisted approach is used to synthesize an efficient electrocatalyst with multiple active components for neutral HER.

Summary: To achieve exceptional electromagnetic wave absorption properties, it is crucial to design the microstructure and modify the components of composites. Metal-organic frameworks (MOFs), with their unique metal-organic crystalline coordination, tunable morphology, high surface area, and well-defined pores, have been recognized as promising precursors for electromagnetic wave absorption materials. However, the inadequate contact abilities between adjacent MOFs nanoparticles result in poor electromagnetic wave dissipation capacity at low filler loading, posing a significant challenge in breaking the size effect of nanoparticles.

Summary: We report an effective catalyst composed of in situ reconstructed AgZn3 nanoparticles and Zn nanoplates for syngas synthesis, showing tunable H2/CO ratios and high Faraday efficiency. Experimental and theoretical results suggest that the Zn site in AgZn3 nanoparticles and the hollow site between Ag and Zn in AgZn3 are the active sites for CO and H2 generation, respectively. This work has important implications for designing dual site catalysts for CO2 electroreduction to tunable syngas.

Summary: The alkaline hydrogen evolution reaction (HER) activity of layered metal hydroxides is optimized by phase engineering and loading Ni nanoparticles, particularly beta-Ni(OH)(2), to improve the electrical conductivity and Volmer step. The constructed heterostructured Ni/beta-Ni(OH)(2) nanosheet arrays (NSAs) exhibit enhanced HER activity and hydrazine oxidation reaction activity compared to Ni/alpha-Ni(OH)(2) NSAs. In hydrazine-assisted water splitting, Ni/beta-Ni(OH)(2) NSAs require a small voltage to achieve high current densities.
