POLYOXOMETALATES COMPRISING NOBLE METALS AND CARBOXYLATE-BASED CAPPING GROUPS AND METAL CLUSTERS THEREOF

摘要

The invention relates to polyoxometalates represented by the formula (An)m+[M′M12Oy(RCOO)zHq]m− or solvates thereof, corresponding supported polyoxometalates, and processes for their preparation, as well as corresponding metal clusters, optionally in the form of a dispersion in a liquid carrier medium or immobilized on a solid support, and processes for their preparation, as well as their use in reductive conversion of organic substrate.
