Molybdate Manganese( MnMoO4 ) microcrytstal has been synthesized via a simple and mild hydrothermal route in the ab-sence of any external inorganic additives or organic structure-directing templates. Powder X-ray diffraction( XRD) and scanning elec-tron microscopy( SEM) are used to characterize the crystallization and particle size and morphology of the obtained MnMoO4 micro-crytstals. MnMoO4 microcrytstals are well crystallized with a uniform morphology. The photocatalytic activity is evaluated by decolor-ization of methyl orange solution under identical conditions. This reaction is nearly comply with a kinetic equation,k≈0. 5 h-1.
