The invention relates to a method for producing lithium-transition metal mixtures of general formula Li(MM)O, wherein Mrepresents nickel, cobalt or manganese, Mrepresents chromium, cobalt, iron, manganese, molybdenum or aluminium, and is different from M, n is 2 if Mrepresents manganese and is 1 otherwise, x is comprised between 0.9 and 1.2, y is comprised between 0.5 and 1.0 and z is comprised between 1.9 and 2.1. According to the inventive method, an intimate mixture composed of transition metal compounds containing oxygen and of a lithium compound containing oxygen is calcinated, said mixture being obtained by processing a solid powder transition metal compound with a solution of said lithium compound, and then drying. At least the Mcompound is used in powder form having a specific surface of at least 20 m/g (BET) and calcination is carried out in a fluidised bed.

Method for producing lithium-transition metal mixtures

The present invention relates to a process for preparing a composition containing gold and/or silver particles and an amorphous, organic/inorganic titanium/silicon mixed oxide, the compositions which can be prepared by this process and their use as catalysts for the selective oxidation of hydrocarbons.

Sol-gel hybrid materials containing precious metals as catalysts for partial oxidation of hydrocarbons

This invention relates to a process for the production of a composition containing gold and/or silver particles, mixed oxides containing titanium and silicon which have been surface-modified, to the compositions producible in this process and to the use thereof in processes for the selective oxidation of hydrocarbons in the presence of oxygen and a reducing agent. The catalytically active compositions exhibit constantly high selectivities and productivities.

Surface-modified mixed oxides containing precious metal and titanium, for the selective oxidation of hydrocarbons

The invention relates to a method for oxidizing hydrocarbons with a hydrogen/oxygen mixture in the presence of a catalyst. The catalyst contains a) a support material which contains titanium and b) silver particles having an average particle size ranging from 0.3 to 100 nm.

Method for oxidizing hydrocarbons

A supported catalyst coated with gold particles is produced. This supported catalyst is used to oxidize unsaturated hydrocarbons in the gas phase with a hydrogen/oxygen mixture.
