Synthesis Of Moo_3 Nanoplates From A Metallorganic Molecular Precursor

摘要

Orthorhombic phase MoO_3 nanoplates were synthesized directly by thermolysis of an air-stable metallorganic molecular precursor (molybdenum diethyldithiocarbamate oxide: Mo((C_2H_5)_2NCS_2)_2O_2, which was prepared simply through the precipitation reaction of ammonium peramolybdate and sodium diethyldithiocarbamate in distilled water under the ambient condition) in air at 350-400℃ for 5 h. The control experiments with ammonium peramolybdate as precursor could only obtain mostly irregular microcrystallites, indicating that the metallorganic molecular precursor, Mo((C_2H_5)_2NCS_2)_2O_2 played an important role in the successful synthesis of MoO_3 nanoplates.
