Abstract: The present invention relates to a layered double hydroxide comprising at least one divalent cation AII or alternatively LiI, at least one trivalent cation BIII selected from the group consisting of VIII, CoIII, CrIII, MnIII FeIII, GaIII and lanthanides. The present invention also relates to a process for the synthesis of said layered double hydroxide and uses thereof.

Abstract: An electrocatalyst, more specifically an electrocatalyst derived from metal-organic framework is provided. An iron zeolitic imidazolate framework, the process for producing it, a graphite carbon nanocomposite containing it and iron nanoparticles, as well as the process for obtaining said nanocomposite from the iron zeolitic imidazolate framework are disclosed herein. Use of the nanocomposite as a catalyst is also disclosed.

Abstract: Soluble homo and heterometallic coordination polymers based on the oxalate ligand and method for obtaining spinels from them. Homo or heterometallic coordination polymers comprising at least one oxalate ligand are characterised by comprising also at least one organic molecule that can stabilise extended structures of metal complexes by the formation of supramolecular interactions so that this polymer is substantially water-soluble and insoluble in organic solvents.

Abstract: The present invention relates to charge injection from metallic conductors to semiconductor or insulation materials based on organic or inorganic molecules and macromolecules with electrical or optical properties, and specifically to a new charge injection layer for electro-optical devices comprising a polymer with conjugated units and a salt mixed with the aforementioned polymer, characterized in that the oxidation state of the polymer is not modified when it is mixed with the salt. Despite the fact that there is no change in the oxidation state of the polymer, the polymer and salt mixture according to the invention makes it possible for a high enough number of charges to reach the optically active layer, such that the efficiency in the charge injection process is increased up to levels exceeding even those provided by the standard PEDOT.
