A one-dimensional polyoxomolybdate polymer as a catalyst for the epoxidation of olefins

Abstract

A one-dimensional coordination polymer, {(NH₄)₄Mo₈O₂₆}_n (1), was synthesized based on polyoxomolybdate nanoclusters under hydrothermal conditions. The crystal structure of the hybrid was determined by single crystal X-ray diffraction analysis. The 1-D coordination polymer 1 was also characterized by FT-IR, powder X-ray diffraction (PXRD), thermogravimetric analysis (TGA) and inductive coupled plasma optical emission spectroscopy (ICP-OES). The catalytic properties of the prepared compound were evaluated in the epoxidation of some olefins using tert-butyl hydroperoxide (TBHP) or H₂O₂ as the oxidant. The 1-D polyoxomolybdate polymer exhibited good activity and stability in the catalytic epoxidation of olefins.
