Abstract

Graphical abstract: Abstract: A series of MnMoP catalysts were prepared by ionic liquid assisted thermal synthesis method and characterized by Powder X-ray diffraction, Fourier Transform Infrared Spectrometer, Scanning Electron Microscope, X-ray Photoelectron Spectroscope and NH3 -Temperature Programmed Desorption. The catalytic performance of MnMoP catalysts for the synthesis of cyclohexene oxide (CHO) was studied. The results showed that phosphorus was fixed via ionic liquid, which could improve the catalytic performance of the catalysts. Under the optimal conditions, MnMoP-80 catalyst showed the best catalytic performance with the cyclohexene conversion of 97.5% and CHO selectivity of 93.9%. Meanwhile, we have deduced that the reaction was mainly carried out according to the epoxidation pathway over MnMoP catalyst.
