Synthesis of Mesoporous CaMoO4 in Aqueous Solution

The mesoporous CaMoO4 microcrystals have been prepared by precipitation in an aqueous solution. The scheelite-type structure in space group I41/a has been verified by the XRD analysis of the final powder product. The CaMoO4 powder is composed of the almost size-uniform erythrocyte-like microspheroids with a diameter of ~5 μm. Every particle is formed by plate-like crystals with the characteristic thickness at a few-nanometer level and a diameter of ~1-2 μm.
