Abstract
Cetylpyridinium phosphomolybdates (Q3[PMo12O40], Q=CetylPy) dispersed on apatite catalyzed H2O2-oxidations of organic compounds under solid-phase conditions without organic solvent. FT-IR and 31P solid-state NMR spectroscopic studies showed the formation of peroxo species in our solid-phase system, which was different from the peroxo type of CetylPy3{PO4[Mo(O)(O2)2]4} (PMo4) known as an active species in the conventional liquid-biphase system. The catalytic activities of them were compared in the solid-phase system.

Keywords: nanocluster catalyst, apatite, organic oxidation, urea-H2O2, solid disperse phase
