A new approach to the synthesis of molybdenum phosphide via internal oxidation and reduction route

A new method for the preparation of molybdenum phosphide was reported. Dispersed MoP with lamellar morphology was obtained from the decomposition of a mixed-salt precursor containing (NH 4) 4Mo 7O 24·2H 2O, (NH 4) 2HPO 4 and hexamethylenetetramine under argon. During the thermal decomposition, reduc...

Description
Summary:A new method for the preparation of molybdenum phosphide was reported. Dispersed MoP with lamellar morphology was obtained from the decomposition of a mixed-salt precursor containing (NH 4) 4Mo 7O 24·2H 2O, (NH 4) 2HPO 4 and hexamethylenetetramine under argon. During the thermal decomposition, reduction of molybdenum and phosphorous species by methane from the hexamethylenetetramine ligand occurred, with release of CO and CO 2. Compared with traditional H 2-temperature-programmed reduction method, the method developed provided a simple one-step way to molybdenum phosphide with relatively high surface area.
