Studies on the nucleation of supersaturated ammonium tetramolybdate solution;

Theoretical calculation on the structure and stability of ammonium tetramolybdate;

The nucleation in the supersaturated solutions of ammonium tetramolybdate prepared from acidified ammonium heptamolybdate solutions is studied in this paper.

Improvement on preparation method of ammonium tetrathiomolybdate;

Characterization of ammonium tetrathiomolybdate as a precursor catalyst for hydropyrolysis;

Sulfide NiMoS/γ-Al2O3 hydrotreating catalyst was prepared through impregnating sulfide precursor ammonium tetrathiomolybdate aqua solution into carrier γ-Al2O3 and the catalyst was investigated by means of XRD and high resolution electron microscopy(HRTEM) to get a better understanding of the nature of the active phase.
