Catalytic behavior of Zn(II) and Co(II) molybdates

Isotopic molybdates of Zn(II) and Co(II) were hydrothermally prepared and the solid products characterized by XRD, TGA, A A, SEM, CHN analysis and N2 adsorption. The materials are layered type and exhibit structures formed by Zn and co octahedrons and molybdenum tetrahedrons with one vertex unconnected, which protrude into the interlayer space. The catalytic behavior was tested by means of the reaction of cyclohexene hydroxylation with hydrogen peroxide. Zn Mo shows high selectivity to 2-cyclohexene-l-ol while Co Mo shows lower activity than the blank
