Summary: This paper describes the structural, electrochemical, and optical properties of two-dimensional copper oxide nanosheets with a length of around 1 μm and a thickness of 30 nm. The nanosheets were prepared using a hydrothermal process with copper nitrate trihydrate as the inorganic precursor and cetyltrimethylammonium bromide (CTAB) as a structure-directing template. Characterization techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), infrared spectroscopy (IR), UV-visible diffuse reflectance spectra (DRS), and room-temperature photoluminescence (RTPL) were used to analyze the samples. The results show that the CuO nanosheets have a monoclinic crystal structure, high phase purity, and nanoscale characteristics. The nanosheets exhibit a higher band gap than bulk CuO due to the quantum confinement effect. The electrochemical properties of the CuO nanoelectrode indicate reversible redox activity, making it a promising electrode material for lithium-ion batteries.

Summary: This study designs a porous carbon-based sulfur electrode for high-energy Li-S batteries. By impregnating the porous carbon with a high concentration of sulfur and reducing the content of conductive agent and binder, crack formation during electrode drying can be inhibited. Two distinct electrically conducting networks are utilized to reduce battery polarization and achieve a capacity of 690 mAh g(-1) even after 100 cycles. Pouch cells are prepared to evaluate the practical performance, resulting in a capacity of 741 mAh and a cathode energy density of 1001 Wh kg(-1). These findings are expected to guide the further development of high-energy-density cathode materials for Li-S batteries.

Summary: In this study, wood-derived hierarchical porous free-standing carbon framework materials were used as three-dimensional conductive current collectors to assemble high-performance lithium-sulfur batteries. The micron-scale pores of wood promote electrolyte diffusion, while the introduction of nanopores on the carbon skeleton inhibits the dissolution and shuttle effect of lithium polysulfide, enhancing the rate and cycle performance of the batteries. The porous carbon framework, with adjustable density, allows for a specific capacity of 1120 mAh/g and good rate performance. After 500 cycles, the capacity decay is only 0.11%/cycle and 0.08%/cycle at 0.5 C and 1 C, respectively. Additionally, wood is a cost-effective and renewable material, and the batteries can be assembled without conventional conductive agents, binders, and current collectors.

Summary: Transition metal oxides (TMOs) have been recognized as promising sensing materials for heavy metal ions (HMIs) detection, mainly due to strong adsorption of HMIs on surface oxygen vacancies (OVs) of TMOs. However, the role of valence change induced redox activity of TMOs in HMIs detection has not received sufficient attention, hindering further development. This study proposes a facile strategy to co-engineer the redox activity and surface OVs of porous Co3O4 nanosheets by Ni doping, achieving enhanced redox activity and adsorption simultaneously. The results demonstrate that the valence change cycle of Co cations plays a more important role in electrochemical detection than the adsorption of Hg(II) on OVs, and Ni-doping facilitates this valence change cycle. This work provides a feasible way to develop TMOs-based sensing materials by synergizing their redox activity and adsorption ability towards HMIs.

Summary: We present a simple method for the preparation of two-dimensional Ni(OH)(2) nanocrystals with varied surface structures by in-situ surface transformation from Ni-MOF in KOH solution at room temperature. Among the samples, Ni(OH)(2) obtained at a KOH concentration of 0.25 M exhibited superior activities and stability. Further investigation attributes the enhanced urea oxidation reaction (UOR) activities to the larger electrochemical surface area, faster electronic transfer speed, and lower transfer resistance on the surface. These findings provide a new route for the rational design and synthesis of advanced electrocatalysts with relatively lower energy consumption for large-scale production and clean energy applications.

Summary: Researchers have long been working on high-performance microwave absorption materials with tunable electromagnetic properties. In this study, two-dimensional MoS2/reduced graphene oxide (MS/RGO) hybrids were constructed through a self-assembled hydrothermal method, showing optimized dielectric behaviors and superior microwave absorption properties with only 20 wt% filler-loading ratio. The composites exhibited wide effective absorption bandwidths, and the improved performance can be attributed to strong interfacial polarization loss, defect dipole polarization, conduction loss, and multiple reflections and scattering. The lightweight MS/RGO composite is considered a promising candidate for high-performance microwave absorbers.
