摘要：

The combined use of temperature-programmed reduction (TPR), Laser-Raman spectroscopy, and X-ray diffraction has provided evidence that phosphoric acid impregnation on γ-alumina, prior to molybdate incorporation, induces the formation of crystalline Al2(MoO4)3 and MoO3 species. These species, absent in the phosphorus-free preparations, are responsible for the appearance of an additional TPR peak at ca. 785 K and also for the development of characteristic Raman bands. © 1990.
