Summary: A new high-nuclear Ti-oxo-cluster-added poly-(polyoxometalate) has been synthesized by reacting two types of trivacant precursors with TiOSO4 under hydrothermal conditions. The resulting compound contains a large {Ti-12}-oxo-cluster cavity sealing a Cs+ ion, which is induced by one Keggin-type [A-alpha-SiW9O34] and three Dawson-type [P2W15O56] fragments. Remarkably, the {Ti-12} cluster is built by three edge-shared Ti3O13 cores and one corner-shared Ti3O15 core bridged via 6 mu(2)-O, which is unprecedented in polyoxometalate chemistry.

Summary: In this study, two new POM-based materials were developed for photocatalytic H-2 evolution, with compound 1 showing significantly higher efficiency compared to compound 2 and bare GeW12 polyanions. The improved performance of compound 1 is attributed to the formation of stable heteropoly blue species, differences in reduction potentials, and good dispersion of GeW12 polyanions.

Summary: Under hydrothermal conditions, two modified Calix[6]arene-like polyoxometalates of the Keggin type were synthesized using precursors such as H3PMo12O40, H3PW12O40, 4H-1,2,4-triazol-3-amine (3-atrz), and copper ions. The two crystalline compounds, 3-atrz-Cu-PW12 and 3-atrz-Cu-PMo12, contained classic Keggin-type polyoxometalate anions and [Cu(C2H4N4)]+ coordination polymers similar to Calix[6]arene. Both catalysts exhibited excellent catalytic activity in the oxidation of iodide ions in hydrogen peroxide, with 3-atrz-Cu-PMo12 showing a significantly higher reaction rate compared to 3-atrz-Cu-PW12. Both catalysts also demonstrated high repeatability with a conversion rate of 99.96% after nine consecutive reactions.

Summary: Five new complexes with metal cations (Mn2+, Fe3+, Co2+, Ni2+, and Cu2+) of monolacunary Keggin monovanado-deca-tungstophosphate, K-8[PVW10O39]center dot 15H(2)O, have been successfully synthesized. The molar ratio of the combination between metal cations and K-8[PVW10O39]center dot 15H(2)O was determined to be 1:1, and their general molecular formulas were found to be K-n[MPVW10O39(H2O)]center dot xH(2)O (n = 5 for M = Fe3+ and n = 6 for M = Mn2+, Co2+, Ni2+, and Cu2+). The optimal conditions for the synthesis of these complexes have been determined, and various characterization methods have been used to confirm their compositions, structures, and properties.

Summary: This study presents a new method for the synthesis of carbon-based transition metal single-atom catalysts using hydrothermal treatment and a mechanochemical method. The hydrothermal treatment results in relatively uniform dispersion of metal ions in the carbonaceous matrix, and compression plays a vital role in the formation and anchoring of the single atom. The prepared catalyst exhibits excellent reactivity performance due to the in-situ formation, unique coordination surroundings, and high content of metal atoms.

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.
