Title
Highly active and selective Cs2.5H0.5PW12O40/SBA-15 composite material in the oxidation of cyclopentane-1,2-diol to glutaric acid by aqueous H2O2
Abstract

In the present work, for the first time the Cs2.5H0.5PW12O40/SBA-15 catalysts were prepared as highly efficient catalysts for the direct production of glutaric acid (GAC) via selective oxidation of cyclopentane-1,2-diol by using aqueous hydrogen peroxide as the green oxidant. The yield of GAC is higher than 88%. The fresh catalyst and the recovered ones were all characterized by XRD, FT-IR, Raman and 31P MAS NMR to reveal the structure change during the reaction. XRD results revealed that the Cs2.5H0.5PW12O40/SBA-15 catalysts keep the crystalline structure of the as-prepared Cs2.5H0.5PW12O40. And it is found that the structure of the Cs2.5H0.5PW12O40/SBA-15 catalysts was retained after the reaction, as determined by Raman, FT-IR and 31P MAS NMR. The new Cs2.5H0.5PW12O40/SBA-15 catalyst can be easily recycled after reaction and can be reused six times, indicating its excellent stability.
