Preparation of MoO3/CuMoO4 nanoparticles as selective catalyst for olefin epoxidation

Thermolysis of the mixture of [cumoo4(n2c12h8)].h2o and [cu3^ icl(4,4'- bipy)4][cu^ii(1,10-phen)2mo8 o26] (4,4'-bipy=4,4'-bipyridine and 1,10-phen=1,10-phenanthroline) coordination polymers has led to the formation of moo3/cumoo4 nanoparticles (nps). the nanomaterial was characterized by means of x-ray di raction (xrd), scanning electron microscopy (sem), energy dispersive x-ray (edx) analysis, dynamic light scattering (dls), and inductive coupled plasma optical emission spectroscopy (icp-oes). the moo3/cumoo4 nps were employed as heterogeneous catalysts in the epoxidation of ole ns and allylic alcohols with tert-butyl hydroperoxide (tbhp) or cumene hydroperoxide (chp) as oxidants in di erent solvents such as chcl3, ch2cl2, and ch3cn. the resulting catalyst displayed high activity and selectivity towards the epoxidation of ole ns and allylic alcohols.
