AI Technical Summary

Technical Problem

Existing catalysts exhibit low advanced oxidation efficiency, poor pollutant removal effect, and limited range of pollutant types when removing pollutants, making it difficult to effectively treat a variety of pollutants.

Method used

A method for preparing ternary transition metal sulfide catalysts was adopted, which involves mixing copper chloride, ferric chloride, and manganese chloride in a solvent and carrying out a hydrothermal reaction to obtain the catalyst. The catalyst is then applied to advanced oxidation, photocatalysis, and electrocatalysis systems, utilizing the synergistic effect between the ternary transition metals to improve the catalytic degradation efficiency.

Benefits of technology

The prepared ternary transition metal sulfide catalyst exhibits excellent degradation effects on antibiotics such as oxytetracycline and tetracycline, as well as dyes such as methylene blue and rhodamine B, in advanced oxidation systems, with removal rates reaching up to 98.8%, 91.1%, 80.3%, and 95.4%, respectively. Furthermore, it is easy to separate and does not easily cause secondary pollution to water bodies, demonstrating good environmental protection and reusability.
