Abstract: New layered double hydroxide materials useful as intermediates in the formation of catalysts are described, as well as methods of preparing the layered double hydroxides. Also described are catalysts suitable for catalysing the hydrogenation of CO2 to methanol, as well as methods for preparing the catalysts. The LDH-derived catalysts of the invention are active in the hydrogenation of CO2 to methanol, and show improved activity with respect to Cu/ZnO catalysts derived from copper-zinc hydroxycarbonate precursors.

Abstract: A process for the preparation of a coated substrate is described, in which a substrate is coated with a coating mixture containing a polymer and an amino acid-modified layered double hydroxide. The process of the invention is markedly simpler than conventional techniques for affording coated substrates having reduced permeability to degradative gases. The coated substrates obtainable by the process are particularly useful in packaging applications, notably in the food industry.

Abstract: Surface-modified layered double hydroxides (LDHs) are disclosed, as well as processes by which they are made, and uses of the LDHs in composite materials. The surface-modified LDHs of the invention are more organophilic than their unmodified analogues, which allows the LDHs to be incorporated in a wide variety of materials, wherein the interesting functionality of LDHs may be exploited.

Abstract: Layered double hydroxides (LDHs) are disclosed, as well as methods by which they may be manufactured. The LDHs are subjected to a solvent treatment step during manufacture, which confers high surface area and pore volume properties to the LDHs. The particular solvents used in the preparation of the LDHs renders allows for an overall more efficient and environmentally-friendly manufacturing process.
