FIELD: heterogeneous catalysts of ozone disintegration used in production with ozone participation: sewage purification, semiconductors treatment in micro electronics, etc. SUBSTANCE: aim is to create catalyst of ozone disintegration, activity of which in dry and moist mediums exceeds activity of known catalyst by 25 and 50 % correspondingly. The aim is achieved due to usage of following composition of catalyst under following ratio of components, %: $$$, 7-20; CuO, 3-10; NiO, 30-50; taluma (calcium mono and dialuminate), 30-40. So, proposed composition of catalyst increases disintegration factor of ozone in dry and moist mediums correspondingly by 25 and 50 %, that allows to get higher degree of gas wastes purification from residual ozone and allows to decrease amount of used catalyst. EFFECT: significant increase of catalyst activity in ozone disintegration. 1 tbl
