ONE-STEP SYNTHESIS OF THERMALLY STABLE SOLID MOLYBDENUM BLUE USING BORON PHOSPHATE

Résumé

For the first time, thermally stable ‘molybdenum blue’ was prepared in a single step, using boron phosphate. Even
though molybdenum blue was discovered more than a century ago, it has not been studied extensively due to its
instability. Presence of variable oxidation states of molybdenum makes it more suitable for catalytic
transformations, but fewer reports are available, since, they were generally prepared in solutions. The present
investigation reports the preparation of stabilized molybdenum blue powder using boron phosphate. The sample was
evaluated for its catalytic activity on the transformation of diphenyl sulfide to sulfoxide selectively, and results were
compared with MoO3 impregnated analog.
