Catalytic Degradation of Wastewater by Amorphous Alloys： Current Status， Influencing Factors， and Modification Strategies

Abstract:

With the rapid development of human society, the discharge of various types of sewage has increased year by year, and environmental problems such as water pollution have become increasingly serious. Seeking effective sewage treatment methods has become an urgent need. Due to its excellent surface activity, low oxidation-reduction potential, and outstanding catalytic degradation performance, amorphous alloys are regarded as effective catalysts for solving various types of wastewater, such as dyeing wastewater. Currently, extensive research has been conducted on the treatment of wastewater containing organic pollutants such as dyes and pesticides, as well as inorganic pollutants such as heavy metals and acid-base salts. However, the degradation mechanism of amorphous alloys varies greatly depending on the type of wastewater and the amorphous alloy system, resulting in different degradation rates. Therefore, selecting suitable amorphous alloy components and appropriate material modification methods is crucial for achieving efficient degradation of wastewater. This review summarized the conventional techniques for wastewater treatment, the characteristics and potential of amorphous alloys, their applications in wastewater treatment, and the existing problems. It also reviewed the influence of various chemical parameters and other factors on the catalytic performance of amorphous alloys, as well as various material modification methods, aiming to provide valuable references for the research of new catalysts.
