  • Patent number: 9012709
    Abstract: The disclosure describes a new class of isomorphously metal-substituted aluminophosphate materials with high phase purity that are capable of performing selective Brönsted acid catalyzed chemical transformations, such as transforming alcohols to olefins, with high conversions and selectivities using mild conditions. Isomorphous substitutions of functional metal ions for both the aluminum ions and the phosphorous ions were successful in various AlPO structures, along with multiple metal substitutions into a single aluminum site and/or a phosphorous site. This invention can be used towards the catalytic conversion of hydroxylated compounds of linear and/or branched moiety with the possibility of being substituted to their respective hydrocarbon products, preferably light olefins containing 2 to 10 carbon atoms, among other chemistries.

  • Patent number: 9011810
    Abstract: An electrode material obtained using a polyol process and a synthesis method is provided. The synthesis method includes steps of preparing a mixed solution by mixing a transition metal compound, a polyacid anionic compound and a lithium compound with a polyol solvent; and obtaining a resultant product by reacting the mixed solution in a heating apparatus. There is an advantage in that the electrode material, which has crystallinity due to a structure such as an olivine structure or a nasicon structure, can be synthesized using a polyol process at a low temperature without performing a heat treatment proces. The nanoelectrode material synthesized by the method has a high crystallinity, uniform particles, and a structure having a diameter ranging from several nanometers to several micrometers. Further, the electrode material has a high electrochemical stability.
