Abstract
The present invention relates to a method of producing particles having a particle size of less than 100 nm and surface areas of at least 20 m2/g where the particles are free from agglomeration. The method involves synthesizing the particles within an emulsion having a 1-40% water content to form reverse micelles. In particular, the particles formed are metal oxide particles. The particles can be used to oxidize hydrocarbons, particularly methane.
Claims10
A composition comprising a material having an average particle size of less than about 100 nm wherein the material, when heated to 700° C. for at least about 10 min, retains an average surface area of at least about 100 m2/g, the material comprising barium hexaaluminate.
