Abstract

The invention discloses a bi-component composite type metallic catalyst and application thereof, the bi-component composite type metallic catalyst comprises a carrier and active components loaded on the carrier. The carrier is active aluminum oxide, the active components are cupric oxide and ruthenium. Compared to the prior art, the preparation of the bi-component composite type metallic catalyst prepared by the invention is simple, though a small amount of precious metals are doped, the catalytic activity of the catalyst can be improved greatly, the costs are low, the activity is good, the application prospect is good. The bi-component composite type metallic catalyst provided by the invention can be used for removing acetophenone in the water by catalytic ozonation, the efficiency of removing acetophenone by ozone can be improved greatly, and the ozone utilization ratio can be improved.

Description

(1) Technical field [0001] The invention relates to a two-component composite metal catalyst and its application, especially the application in catalyzing ozone oxidation to remove acetophenone from water. (2) Background technology [0002] In recent years, with the rapid development of industry, the wastewater discharged by industry has also shown the characteristics of complex components, producing a large number of new, non-biodegradable, toxic and harmful organic pollutants, which are difficult to treat by general treatment methods. [0003] As a clean and strong oxidant, ozone has been widely used in the treatment of drinking water and industrial sewage, but the oxidation of ozone has certain selectivity, and the oxidation of organic matter is not thorough enough. To solve the above problems, in recent years, advanced Oxidation technology, that is, in the process of treatment, promotes the decomposition of ozone to produce an efficient and non-selective strong oxidant O...
