METHOD FOR PRODUCING PHOTOCATALIZER BASED ON A MECHANOACTIVATED POWDER OF ZINC OXIDE Russian patent published in 2017 - IPC B01J37/00 B01J23/06 B22F9/04

Abstract RU 2627496 C1

FIELD: nanotechnology.

SUBSTANCE: invention relates to methods for producing photocatalysts for the decomposition of substances polluting air and water, and can be used in the chemical, pharmaceutical and biosynthetic industries. The method is that the ZnO powder is subjected to intensive mechanical treatment in air. At the same time, the grinding speed in the grinding drums of a planetary ball mill is 250 rpm, the ratio of powder mass and balls is 10:1, the grinding time is 1 minute.

EFFECT: due to mechanoactivation of zinc oxide powders with specified process parameters, their photocatalytic activity increases.
