Including results for Effects of Cs and V on heteropoly acid catalysts in methacrolein oxidation
Jul 23, 2024 ˇ The increase in V4+ species, terminal oxygen Od, and bridging oxygen OB means that 50(DMDAAC)CsPAV/SiO2 had stronger redox properties than 50CsPAV/SiO2. The ...
Jan 5, 2024 ˇ Among these steps, the oxidation of MAL to MAA is a key step, in which P-Mo-V-based heteropolyacid cesium salt catalysts have been widely utilized.
Jun 6, 2024 ˇ The application of heteropoly acid catalyst in methacrolein (MAL) oxidation reaction is limited for its poor thermal stability and few active centers. Here, the ...
Jan 25, 2024 ˇ This suggests that Cs+ modification improved HPW dispersion and partially neutralized strong acid sites, enhancing catalytic performance. In 2018, Chen et al. [ ...
5 days ago ˇ Besides, adjusting the relationship between reactive metal and heteroatoms improves catalytic stability by preventing leaching, sintering, and agglomeration.
Apr 9, 2024 ˇ Heteropolyacids (HPAs) function as promising catalysts due to their cost-effectiveness, ease of handling, and reducing toxicity in comparison to corrosive and ...
Sep 21, 2024 ˇ The catalytic selective oxidation of isobutane to methacrolein (MAC) and methacrylic acid (MAA) is known to proceed via a Mars-Van Krevelen mechanism.
Nov 1, 2024 ˇ The heteropolyacids are compounds in which one atom of such elements as P, Si, As, B, Al, etc., is combined with a number of atoms of an element such as W or Mo ...
Apr 25, 2024 ˇ Supported Rb- or Cs-containing HPA catalysts for the selective oxidation of isobutane. ... oxidation into acetic acid over a Mo-V-Nb mixed oxide catalyst.
Feb 22, 2024 ˇ The purpose of this study was to study the kinetics of the toluene oxidation process and establish the mechanism of the process. For the first time, catalytic ...
