AI Technical Summary
In existing advanced oxidation technologies, single metal oxide catalysts have limited active sites, slow reaction kinetics, easy dissolution of metal ions leading to secondary pollution and insufficient cycle stability. High-entropy oxides have complicated synthesis processes, component segregation and limited specific surface area, making it difficult to meet the broad-spectrum adaptability requirements of complex component pollutants.
Using Prussian blue analogues as precursors, high-entropy mixed metal oxides are prepared by one-step calcination and pyrolysis, achieving uniform mixing of multiple metal ions, simplifying the preparation process and improving catalytic activity.
The prepared high-entropy mixed metal oxides exhibit far superior catalytic activity compared to traditional single-metal or simple bimetallic oxides when catalyzing the degradation of organic pollutants by persulfate, and the process is simple and easy to scale up.
