摘要：

Molybdenum blue dispersions are synthesized via the reduction of molybdate with glucose in an acidic medium. Spectrophotometry and photon correlation spectroscopy show that, depending on the reducing agent/molybdate ratio and the pH value, both colored complex Mo compounds and dispersed phase particles (large molybdenum oxide clusters) can form. It is shown that particles form in the 1.4-2.2 range of the dispersion medium's pH and ceases 21 days after synthesis (at room temperature).
