1results about How to "Efficient oxidative degradation" patented technology

This invention relates to a selenium-iron-copper composite catalyst material, its preparation method, and its applications in the field of materials chemistry. The catalyst uses ferric oxide as a matrix, with selenium powder, iron powder, and copper powder added as active components, and polyol and carboxylic acid as auxiliary agents. The process involves premixing, calcination, and pulverization. The selenium powder content is 1-7 wt% of ferric oxide, the iron powder content is 2-10 wt%, and the copper powder content is 0.5-1.5 wt%. The preferred polyol is glycerol, and the preferred carboxylic acid is crotonic acid. The calcination temperature is 400-800℃. In catalytic testing, under room temperature and air bubbling conditions, this catalyst can achieve a degradation rate of over 90% for tetracycline hydrochloride within one hour. This invention features a simple preparation method, low cost, high catalytic activity, mild operating conditions, and efficient degradation of tetracycline in water, making it suitable for antibiotic wastewater treatment.
