Mg-based amorphous alloys exhibit efficient catalytic performance and excellent biocompatibility with a promising application probability, specifically in the field of azo dye wastewater degradation. However, the problems like difficulty in preparation and poor cycling stability need to be solved. At present, Mg-based amorphous alloys applied in wastewater degradation are available in powder and ribbon. The amorphous alloy powder fabricated by ball milling has a high specific surface area, and its reactivity is thousands of times better than that of gas atomized alloy powder. But the development is limited due to the high energy consumption, difficult and costly process of powder recycling. The single roller melt-spinning method is a new manufacturing process of amorphous alloy ribbon. Compared to amorphous powder, the specific surface area of amorphous ribbon is relatively lower, therefore, it is necessary to carry out surface modification to enhance it. Dealloying is a way that can form a pore structure on the surface of the amorphous alloys, increasing the specific surface area and providing more reactive sites, which all contribute to the catalytic performance. Exploring the optimal conditions for Mg-based amorphous alloys in wastewater degradation by adjusting amorphous alloy composition, choosing suitable method to preparation and surface modification, reducing cost, expanding the pH range will advance the steps to put Mg-based amorphous alloys in industrial environments into practice.

镁基非晶合金处理偶氮染料废水的进展与展望

镁基非晶合金表现出高效的催化性能和优异的生物相容性，特别是在偶氮染料废水降解领域具有广阔的应用前景。但其制备难度大、循环稳定性差等问题亟待解决。目前应用于废水降解的镁基非晶合金有粉末状和带状两种。球磨制备的非晶合金粉末具有很高的比表面积，其反应活性比气雾化合金粉末好数千倍。但由于粉体回收过程能耗高、难度大、成本高，发展受到限制。单辊熔融旋压法是一种非晶合金带材制造新工艺。与非晶粉末相比，非晶薄带的比表面积相对较低，因此需要进行表面改性来提高其比表面积。脱合金是一种可以在非晶合金表面形成孔隙结构、增加比表面积并提供更多反应位点的方法，这些都有助于提高催化性能。通过调整非晶合金成分、选择合适的制备方法和表面改性、降低成本、扩大pH范围等探索镁基非晶合金废水降解的最佳条件，将推进镁基非晶合金在工业环境中的应用。实践。
