Metal-molybdate and method for making the same

Abstract

A process for producing a metal-molybdate material is provided. The process includes a step of reacting a metal molybdenum (Mo) material in a liquid medium with a first acid to provide a Mo composition and combining the Mo composition with a metal source to provide a metal-Mo composition. The metal-Mo composition can be pH adjusted with a base to precipitate a plurality of metal-Mo particulates.

         1 . A metal-molybdate (metal-Mo) prepared by a process, the process comprising:
 reacting a metal molybdenum (Mo) material in a liquid medium with a first acid to provide a Mo composition;   combining the Mo composition with a metal source to provide a metal-Mo composition; and   pH adjusting the metal-Mo composition with a base to precipitate a plurality of metal-Mo particulates.   
     
     
         2 . A metal-molybdate (metal-Mo) prepared by a process, the process comprising:
 oxidizing, in whole or in part, a metal molybdenum (Mo) material in a liquid medium with a first acid to provide a Mo composition;   combining the Mo composition with a metal source to provide a metal-Mo composition; and   pH adjusting the metal-Mo composition with a base to precipitate a plurality of metal-Mo particulates.   
     
     
         3 . A metal-molybdate (metal-Mo) material, comprising:
 a plurality metal-Mo particulates comprising at least one bond between a metal, metalate, or a metallic salt, and a molybdate of the metal-Mo particulates, and   wherein the bond is in a form of an oxo-bridge, a hydroxo-bridge, or a combination thereof.   
     
     
         4 . The material of  claim 3 , wherein an average size of the plurality of metal-Mo particulates is in a range of from about 10 microns to about 1275 microns.
