Summary: The synthesis and characterization of hematite (& alpha;-Fe2O3) nanoparticles (NPs) were conducted, and their photocatalytic properties were studied. The α-Fe2O3 NPs were found to have a rhombohedral phase confirmed by XRD, and FT-IR was used to analyze functional groups on the catalyst surface. The bandgap energy was determined to be 2.25 eV using UV-Vis DRS, and SEM images showed a spherical morphology. The α-Fe2O3 NPs exhibited oxidation and reduction properties as analyzed by CV. Under natural sunlight, the degradation efficiency of methylene blue (MB) dye using the α-Fe2O3 NPs reached 33% in 2 hours, with a pseudo-first-order rate constant of 0.0033 min(-1).

Summary: In2S3 materials doped with different concentrations of copper ions (Cu-In2S3) were synthesized and showed improved response to visible light, carrier separation, and adsorption for rhodamine B. Cu-doping enhanced the photocatalytic activity of In2S3 for dye removal, with 0.3% Cu2+-doped In2S3 exhibiting the highest activity and stability. Superoxide radicals were identified as the main active species in the photocatalytic degradation of rhodamine B over 0.3% Cu-In2S3. This study provides valuable insights for the construction of In2S3-based photocatalytic materials.

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.
