Summary: This study focuses on the ligand-engineering strategy to optimize the electronic structure of Ni-MOFs by incorporating electron-rich ferrocene unit. The resulting Ni-MIL-53-Fc shows significantly enhanced electrochemical oxygen evolution reaction (OER) activity compared to Ni-MIL-53-NH2, with a 6.6-fold improvement in TOF value at an overpotential of 350 mV. Characterizations further confirm that the introduction of Fc unit enhances charge transfer, leading to more electrons aggregated in the Ni active sites and improving the intrinsic OER activity of Ni sites. This ligand-engineering strategy can be extended to fabricate highly active and stable catalysts for other electrocatalytic reactions.

Summary: This study successfully achieves the heterogenization of homogeneous Ni-based molecular catalyst with the solid Fe-MIL-53-NH2 framework by covalently grafting, effectively integrating the advantages of homogeneous and heterogeneous catalysis. Electrochemical results indicate that the overpotential in NiN2Cl2@Fe-MIL-53 for the oxygen evolution reaction (OER) is significantly lower than that in Fe-MIL-53-NH2, confirming the key active sites of the Ni-based molecular catalyst. Kinetic analysis shows that the Eapp in the Ni-based molecular catalyst is much lower than that in NiN2Cl2@Fe-MIL-53, demonstrating the improved OER activity by regulating the rate-determining step with the incorporation of the Ni-based molecular catalyst.

Summary: A low-temperature salt-assisted chemical vapor deposition method was used to grow single-domain Bi2O2Se on a millimeter scale with multilayer to monolayer thickness. The layer-dependent Raman spectroscopy of Bi2O2Se was systematically investigated, showing a redshift of the A(1g) mode at 162.4 cm(-1). The environmental stability of approximately 2.4 nm thick Bi2O2Se was confirmed after exposure to air for 1.5 years. The backgated field effect transistor based on a few-layered Bi2O2Se exhibited decent carrier mobility (approximately 287 cm(2) V(-1)s(-1)) and an ON/OFF ratio of up to 10(7), indicating a technique for growing large-domain thickness controlled Bi2O2Se single crystals for electronics.

Among them, HOF-ZSTU-2 forms a strong layered hydrogen-bonding network with ammonium (NH4+) through multiple carboxyl groups and has a suitable 1D pearl-chain channel for the selective capture of propylene (C3H6). HOF-ZSTU-2 achieves a C3H6 storage density of 0.6 kg L-1 at 298 K and 1 bar, and exhibits a propylene/propane (C3H6/C3H8) selectivity of 12.2.

Summary: Mixed transition metals and their oxides have attracted significant research attention due to their wide range of applications in electronics, magnetism, and electrochemical energy storage and conversion devices. In this study, CoMn2O4 spinel oxide was synthesized through the auto-combustion method, with the structure and phase purity confirmed by X-ray diffraction. The oxide and hydroxyl groups were identified as the major active sites through Fourier transform infrared spectroscopy. The synthesized sample exhibited near-infrared light activity with a bandgap of 1.3 eV, as determined by UV-Vis spectroscopy. The average particle size of CoMn2O4 was found to be 161 +/- 26 nm through scanning electron microscopy. X-ray photoelectron spectra showed a mixed spinel structure containing Co and Mn cations. Magnetic investigations revealed a ferrimagnetic response in CoMn2O4 and the emergence of a large exchange bias above the transition temperature due to the presence of Griffiths phase.

Summary: An efficient method for phosphate removal from wastewater is urgently needed due to the environmental issue caused by excessive phosphorus. In this study, calcium aluminum layered double hydroxides (CaAl-LDHs) and six amino acid intercalated calcium aluminum layered double hydroxides (CaAl-amino acid-LDHs) were prepared and compared for their phosphate adsorption performance. L-Aspartic acid intercalated calcium aluminum layered double hydroxides (CaAl-Asp-LDHs) exhibited the highest phosphate adsorption capacity and faster removal rate compared to CaAl-LDHs. The phosphate adsorption mechanism on CaAl-Asp-LDHs involved electrostatic attraction, hydrogen bonds, complexation, and ion exchange. This environmentally friendly material shows promising potential for efficient phosphate removal from aquatic environments.

Summary: Studying the diffusion properties of hydrogen is important for designing new proton conductors. In the past, the chemical diffusion coefficient of hydrogen in proton conductors was usually obtained through a manual calculation method, resulting in difficulty in controlling the calculation accuracy. To address this issue, a mathematical algorithm and C language computer program were developed to calculate the chemical diffusion coefficient based on Fick's second law and Romberg numerical integral. The algorithm showed high precision and powerful computing function, and has the potential to replace the manual calculation method in calculating the chemical diffusion coefficient for hydrogen in proton conductors.
