摘要：

Laser Raman Spectra of molybdena supported at different concentration on the surface of gamma-Al2O3 prepared by both impregnation and physical mixtures- have been recorded. Formation of polymolybdate species, depending on Mo loading and time and temperature of calcination, has been detected in both series of samples.
