摘要:A method is provided for the synthesis of a mesoporous lithium transition metal compound, the method comprising the steps of (i) reacting a lithium salt with one or more transition metal salts in the presence of a surfactant, the surfactant being present in an amount sufficient to form a liquid crystal phase in the reaction mixture (ii) heating the reaction mixture so as to form a sol-gel and (iii) removing the surfactant to leave a mesoporous product. The mesoporous product can be an oxide, a phosphate, a borate or a silicate and optionally, an additional phosphate, borate or silicate reagent can be added at step (i). The reaction mixture can comprise an optional chelating agent and preferably, the reaction conditions at steps (i) and (ii) are controlled so as to prevent destabilization of the liquid crystal phase. The invention is particularly suitable for producing mesoporous lithium cobalt oxide and lithium iron phosphate. The method can be used to synthesize mesoporous lithium cobalt oxide having a specific surface area in excess of 10 m 2 /g, preferably 15 m 2 /g or more.

权利人:CIBA SC HOLDING AG
摘要:N-(Hydroxyalkoxy) hindered amine stabilizers are prepared by reacting the corresponding N-oxyl compound with a peroxide or organic hydroperoxide and a catalytic amount of a metal salt or metal-ligand complex in an alcohol solvent. These N-(hydroxyalkoxy) hindered amines are particularly useful as stabilizers for polyolefins, thermoplastic polyolefins and automotive coating compositions.

摘要:The present disclosure includes a method for preparing an aqueous dispersion of γ-Fe 2 O 3 nanoparticles. The method includes grinding an iron (II) hydrated salt, an iron (III) hydrated salt, an inorganic salt, and alkali hydroxide in a grinding or milling machine. The inorganic salt may be a salt matrix that prevents growth and aggregation of the synthesized nanoparticles. The aqueous dispersion of γ-Fe 2 O 3 nanoparticles may optionally be hydrothermally treated to become an aqueous dispersion of α-Fe 2 O 3 nanoparticles. Also disclosed is a method for preparing an mixture of α-Fe 2 O 3 nanoparticles and γ-Fe 2 O 3 nanoparticles, in which at least an iron (III) hydrated salt, an inorganic salt, and alkali hydroxide are ground in a grinding or milling machine. Uses for the nanoparticles include: a magnetic resonance image contrast agent, a color print ink, an artificial tanning pigment, a photocatalyst for degradation of organic dye, a red pigment, an adsorbent for waste water treatment, a catalyst support, and a catalyst.

摘要:The invention relates to a continuous process for preparing carbon-coated lithium-iron-phosphate particles, wherein the carbon-coated lithium-iron-phosphate particles have a mean (d 50 ) particle size of 10 to 150 nm, and wherein the carbon-coating is an acetylene-black coating, comprising performing in a reactor a flame-spray pyrolysis step (i) in a particle formation zone of the reactor, and a carbon-coating step (ii) in a carbon-coating zone of the reactor, wherein inn (i) a combustible organic solution containing a mixture of lithium or a lithium compound; iron or an iron compound; and phosphorus or a phosphorous compound in an organic solvent, is fed through at least one nozzle where said organic solution is dispersed, ignited and combusted, to give a flame spray thereby forming an aerosol of lithium iron phosphate particles; (ii) acetylene gas is injected into said aerosol thereby forming an acetylene-black coating on the lithium iron phosphate particles; (iii) the coated particles are cooled by an inert quench gas and collected on a filter.

摘要:The present application discloses a method of forming an inorganic macroporous material. In some embodiments, the method includes: providing a sample of organic polymer particles having a particle size distribution of no greater than about 10%; forming a colloidal crystal template of the sample of organic polymer particles, the colloidal crystal template including a plurality of organic polymer particles and interstitial spaces therebetween; adding an inorganic precursor composition including a noncolloidal inorganic precursor to the colloidal crystal template such that the precursor composition permeates the interstitial spaces between the organic polymer particles; converting the noncolloidal inorganic precursor to a hardened inorganic framework; and removing the colloidal crystal template from the hardened inorganic framework to form a macroporous material. Inorganic macroporous materials are also disclosed.
