A novel POM/LDH/GO nanocomposite as highly efficient heterogeneous catalyst in green epoxidation of alkenes with hydrogen peroxide
In the present work, various transition metal substituted Keggin-type polyoxometalates/Ni-Al layered double hydroxide/graphene oxide (PWM/Ni-Al LDH/GO; M = Fe, Ni, Cu, Mn, Co, Cr, Zn) nanocomposites have been synthesized and utilized as catalysts in the epoxidation of alkenes. Results confirmed that...

| description | In the present work, various transition metal substituted Keggin-type polyoxometalates/Ni-Al layered double hydroxide/graphene oxide (PWM/Ni-Al LDH/GO; M = Fe, Ni, Cu, Mn, Co, Cr, Zn) nanocomposites have been synthesized and utilized as catalysts in the epoxidation of alkenes. Results confirmed that in the epoxidation of alkenes, PWFe/Ni-Al LDH/GO nanocomposite could perform its role as the best catalyst. The selected nanocomposite evaluated as a heterogeneous catalyst in the green oxidation of various alkenes into the corresponding epoxides while aqueous hydrogen peroxide was used as an environmentally benign oxidant. The results of recovery and reusability experiments on PWFe/Ni-Al LDH/GO nanocomposite revealed that even after five times it could be easily reused without any considerable decrease in catalytic efficiency. |
