METHOD OF PRODUCING NANOSTRUCTURED METAL OXIDE COATINGS Russian patent published in 2014 - IPC B01J13/00 C01G1/02 B82B3/00 B82Y30/00 B82Y40/00 

FIELD: chemistry.

SUBSTANCE: method comprises preparing an alcohol solution of β-diketonates of one or more p-, d- or f-metals with concentration 0.001h² mol/l; heating the solution to 368-523 K and holding at said temperature for 10-360 minutes to form a metal alkoxo-β-diketonate solution; depositing the obtained solution in droplets at the centre of a substrate being rotated at a rate of 100-16000 rpm, or immersing the substrate into said solution at a rate of 0.1-1000 mm/min at an angle of 0-60° to the vertical; holding the substrate with a film of the alkoxo-β-diketonate solution at 77-523 K until mass loss ceases, to form xerogel on the surface of the substrate; crystallising oxide from the xerogel at 573-1773 K.

EFFECT: invention enables to obtain single- or multilayer dense and porous, amorphous and crystalline nanostructured oxide coatings with ordered particle size ranging from 1 nm to 100 nm with given functional properties.
