Description 656-662
Molybdenum- and tungsten-containing (M7O246-, M = Mo or W) layered double hydroxides (LDHs) with Mg2+ and Al3+ cations in the brucite-like layer have been prepared by direct anion exchange, starting from the corresponding terephthalate precursor. The solids have been characterized by various instrumental techniques such as elemental chemical analysis, powder X-ray diffraction, infrared spectroscopy, scanning electron microscopy, transmission electron microscopy and thermogravimetric analysis. The M7O246- intercalated LDHs have been explored as catalysts for the selective oxidation of a series of alkenes at room temperature using safer, inexpensive and environmentally benign hydrogen peroxide as oxidant. Reaction conditions have been optimized considering different reaction parameters to achieve maximum conversion in the catalytic oxidation reaction. Recycling of the catalyst has shown that it can be reused up to three more cycles without significant loss of performance.
