Summary: Heteroanionic compounds composed of oxygen and tellurium anions provide opportunities for discovering new phases and tuning physical properties. In this study, oxytelluride Ln2O2Te (Ln = La-Pr) compounds are synthesized and a reversible phase transition between oxytelluride and tellurate is observed upon heating. The instability of Ce2O2Te under ambient conditions is demonstrated as it decomposes to form CeO2.

Summary: This study synthesized a series of Pt-Ln/C (Ln = La, Ce, Pr, Nd) nanoalloy catalysts to enhance the electroactivity towards methanol oxidation and suppress the CO poisoning effect of Pt. Among them, Pt5Ce/C showed the best performance with 11.1 times higher specific activity compared to commercial Pt/C. The work demonstrates the critical promotion effect of lanthanide elements in the electroactivity of Pt, providing new ideas for designing efficient lanthanide alloy catalysts.

Summary: In this study, the structure and CO activation mechanism of mononuclear lanthanide (Ln) oxocarbonyl complexes OLn(12-CO) were investigated. It was found that the excitation of CO is related to the intramolecular charge transfer between the cationic LnO and CO, rather than the typically accepted metal-CO back-donation.

Summary: La2O2S2 has been used recently as a precursor for the preparation of either a new metastable form of La2O2S or quaternary compounds. The crystal structure of the precursor material is still a matter of debate, with different structural models reported in the literature. The crystal structures of La2O2S2, Pr2O2S2, and Nd2O2S2 are revisited in this study, proposing an alternative model that reconciles pre-existing structural descriptions and highlights the strong dependency on synthesis conditions.

Summary: Zinc telluride is a versatile wide band gap semiconductor used in many applications, but it has limitations in terms of size and band gap. Introducing alkali metal and lanthanide to its lattice can reduce dimensions and cause a red shift in the energy gap. CsLnZnTe3 compounds, formed by incorporating alkali and lanthanide into zinc tellurides, exhibit layered crystal structure with direct band gaps. The band gaps of these compounds have not been evaluated yet, and calculations were also performed for energy loss functions, refractive index, and dielectric functions to explore their potential applications in optoelectronic devices.

Summary: Lanthanoid oxysulfides were synthesized and characterized, and their electronic and photophysical properties were thoroughly discussed. The oxysulfides were found to have direct band gaps and exhibit n-type semiconductor behavior, with mid-band gap states possibly arising from 4f orbitals and crystal structure defects. These findings suggest possible applications of the oxysulfides in photoelectrochemical and photovoltaic energy conversion.

Summary: This study reports for the first time a class of cubic Mn-Ln bimetallic MOFs with excellent thermal and electrochemical stability. The enhanced Li+ adsorption capability of these MOFs is attributed to the opening of their ultra-micropores during cycling. This work enriches the understanding and development of stable MOFs for highly stable LIBs.

Summary: Ni/LnO(x)-type catalysts were prepared and characterized for the dry reforming of biogas. LNO showed higher catalytic activity compared to other materials. However, it suffered from significant activity loss and reactor blockage. The deactivation was attributed to extensive coke deposition, including disordered carbon and multi-walled carbon nanotubes.

Summary: A series of CaAlSiN3:Ln (Ln=Eu, Ce, Dy, Pr, Tb, Gd, Sm, Tm, Nd) phosphors were successfully prepared by combustion synthesis, and their polychromatic visible afterglow emissions were observed. CaAlSiN3:Eu2+ and CaAlSiN3:Ce3+ showed the best red and yellow long persistent luminescence with persistent times of 4980 s and 4860 s, respectively. Eu2+, Ce3+ co-doped CaAlSiN3 exhibited enhanced red long persistent luminescence with a persistent time of 6300 s, attributed to a more appropriate trap depth distribution.

The structures were determined by single-crystal X-ray diffraction, with the band gaps of La-2(IO3)(3)(IO4) and Nd-2(IO3)(3)(IO4) estimated to be 3.0 and 3.4 eV. La-2(IO3)(3)(IO4) was used as a host matrix for Eu, Tb, and Dy doping to introduce luminescence.

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.
