“…In addition, in our previous research, we also found an anomalous phase transition in the Mo(VI)-containing phosphates, which would imply a potential application in negative expansion materials . However, remarkably, up to now only dozens of Mo(VI)-containing phosphates have been reported. ,− Further exploration of Mo(VI)-containing phosphates is still of scholarly and technological interest.…”

Mo(VI)-containing phosphates are widely used in catalyses, ion batteries, and nonlinear optical (NLO) crystals. However, few strategies can effectively guide the syntheses of the Mo(VI)-containing phosphates. In this paper, three new Mo(VI)-containing phosphates, Cs3Mo12PO40, LiK(MoPO6)2, and Sr(MoPO6)2, with different dimensions have been successfully synthesized by adjusting the Mo/P ratios. Interestingly, Cs3Mo12PO40 is a classic Keggin-type polyoxometalate composed of zero-dimensional (0D) [Mo12PO40]3– clusters, whereas LiK(MoPO6)2 and Sr(MoPO6)2 have three-dimensional (3D) [MoO2O4P]∞ frameworks consisting of MoO6 octahedra and PO4 tetrahedra in a 1/1 ratio. Detailed structural comparisons of Mo(VI)-containig phosphates indicate that the Mo/P ratios have a significant effect on the structural dimensions. Further, the optical properties and thermal stabilities of Cs3Mo12PO40, LiK(MoPO6)2, and Sr(MoPO6)2 are also determined.

“…Since all of the compounds used for synthesis were of analytical quality, additional purification was not necessary. The synthesis of the precursor MoO 2 ·HPO 4 ·H 2 O followed the instructions in the literature. − The schematic of the synthesis process is represented in Figure . Initially, at about 180 °C, 15 g of MoO 3 (Alfa Aesar, 99.5%) were mixed in 45 mL of 88% phosphoric acid (Merk) on a magnetic stirrer at 500 r.p.m.…”

Mo₂P₂O₁₁: A Potential Cathode Material for Rechargeable Sodium-Ion Batteries

et al. 2022

Due to the limiting lithium reserve and increasing price of lithium, alternatives to Li-ion batteries are growing rapidly. The world is now focusing on developing electrodes beyond Li-ion-based rechargeable batteries for portable electronics. Iron, nickel, and Co-based NASICON structured materials give stable capacity with reversible intercalation of almost one sodium in the host lattice. In the current work, we suggest a cathode material made of 3D framework-structured molybdenum polyanionic phosphate (Mo2P2O11) for a reversible sodium-ion battery. Mo2P2O11 was synthesized using the heat treatment of the MoO2HPO4·H2O precursor at 560 °C, having the morphology of stacked flakes. Characterization techniques such as X-ray diffraction, Fourier transform infrared spectroscopy, thermogravimetric analysis, X-ray photoelectron spectroscopy, scanning electron microscopy, and energy-dispersive X-ray were utilized for confirming the structure and morphology of the materials. For electrochemical performance, cyclic voltammetry, charge–discharge, and stability tests have been performed. Mo2P2O11 work through the active participation of the Mo6+/4+ redox couple with reversible intercalation of Na+ ions. The electrode exhibits reversible intercalation at 3.0 V versus Na and a steady capacity of ∼90 mA h/g, that is, ∼1.4 Na per formula unit, achieving a Coulombic efficiency of nearly 100%. The current finding opens up a new route for using transition-metal phosphates as efficient and stable charge storage cathode materials for sodium-ion batteries.

“…In order to selectively produce the olefins or the oxygenates, mixed-metal oxide or phosphate heterogeneous catalysts based on molybdenum and vanadium redox-active species have been used, such as MoVTeNbO x and the state of the art industrial catalyst for n -butane selective oxidation, vanadyl pyrophosphate. Several recent investigations have explored the physicochemical properties and the catalytic activity of mixed-metal phosphates in a systematic way …”

The design of heterogeneous catalysts is challenged by the complexity of materials and processes that govern reactivity and by the fact that the number of good catalysts is very small in comparison to the number of possible materials. Here, we show how the subgroup-discovery (SGD) artificial-intelligence approach can be applied to an experimental plus theoretical data set to identify constraints on key physicochemical parameters, the so-called SG rules , which exclusively describe materials and reaction conditions with outstanding catalytic performance. By using high-throughput experimentation, 120 SiO 2 -supported catalysts containing ruthenium, tungsten, and phosphorus were synthesized and tested in the catalytic oxidation of propylene. As candidate descriptive parameters, the temperature and 10 parameters related to the composition and chemical nature of the catalyst materials, derived from calculated free-atom properties, were offered. The temperature, the phosphorus content, and the composition-weighted electronegativity are identified as key parameters describing high yields toward the value-added oxygenate products acrolein and acrylic acid. The SG rules not only reflect the underlying processes particularly associated with high performance but also guide the design of more complex catalysts containing up to five elements in their composition.
