Surface state of molybdenum cations in MoO3/CeO2

Conclusion

  1. 1

    The dispersion capacity of MoO3 supported on CeO2 is 0.81 rnmo1/100 m2. For samples with MoO3 content is below the dispersion capacity, Mo6+ ions exist in the surface vacancies to form the surface Mo species, and the highly dispersed Mo6+ cations are coordinated by 7 oxygen ions based on the assumption that the CeO2(111) plane is preferentially exposed.

  2. 2

    The differences of the dispersions between MoO3 on CeO2 and MoO3on ZnO-modified CeO2 indicate that the surface vacancies play an important role in the dispersion of MoO3.
