Metallic glasses have recently attracted great attention in terms of degrading dyes and other organic pollutants as an environmentally friendly material for wastewater remediation. Herein, we report a new type of amorphous catalyst Fe₄₁Co₇Cr₁₅Mo₁₄C₁₅B₆Y₂ hollow balls. Results demonstrate that the catalyst can still completely decolorize the 20 mg/L methylene blue (MB) solution after reused for 50 times under conditions of pH = 5, catalyst content 0.5 g/L, and temperature 80 °C. The catalyst is easily broken during degradation, so the inner surface also provides additional active sites. The Fe₄₁Co₇Cr₁₅Mo₁₄C₁₅B₆Y₂ amorphous alloy hollow balls were characterized by energy dispersive X-ray specroscopy (EDS), scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS), respectively. The elements in the catalytic system have a synergistic catalytic effect. Redox cycle Fe²⁺/Fe³⁺, Co²⁺/Co³⁺ and Mo⁴⁺/Mo⁶⁺ promote mutual conversion and accelerate the catalytic process of their reaction with H₂O₂, forming a self-stable redox cycle process. Among them, Fe²⁺ promotes the conversion of Co³⁺ to Co²⁺, and Mo⁴⁺ promotes the conversion of Fe³⁺ to Fe²⁺, mainly Fe²⁺ and Co²⁺ react with H₂O₂ to generate •OH. Mo and Cr elements form MoO₂ and Cr₂O₃ plasma compounds on the surface, which act as a protective film to make the catalyst more stable and be repeated used more frequently.

金属玻璃最近在降解染料和其他有机污染物方面引起了极大的关注，作为一种用于废水修复的环保材料。在此，我们报道了一种新型非晶催化剂Fe ₄₁ Co ₇ Cr ₁₅ Mo ₁₄ C ₁₅ B ₆ Y ₂空心球。结果表明，在pH = 5、催化剂含量0.5 g/L、温度80 ℃的条件下，该催化剂重复使用50次后仍能完全脱色20 mg/L亚甲蓝（MB）溶液。催化剂在降解过程中很容易被破坏，因此内表面也提供了额外的活性位点。Fe ₄₁ Co ₇ Cr₁₅ Mo ₁₄ C ₁₅ B ₆ Y ₂非晶合金空心球分别通过能量色散X射线光谱(EDS)、扫描电子显微镜(SEM)和X射线光电子能谱(XPS)表征。催化体系中的元素具有协同催化作用。氧化还原循环Fe ²⁺ /Fe ³⁺、Co ²⁺ /Co ³⁺和Mo ⁴⁺ /Mo ^{6+促进相互转化，加速它们与H} ₂ O ₂反应的催化过程，形成自稳定的氧化还原循环过程. 其中，Fe ²⁺促进Co ³⁺向Co ²⁺的转化，Mo ⁴⁺促进Fe ³⁺向Fe ²⁺的转化，主要是Fe ²⁺和Co ²⁺与H ₂ O ₂反应生成•OH。Mo和Cr元素在表面形成MoO ₂和Cr ₂ O ₃等离子化合物，起到保护膜的作用，使催化剂更稳定，重复使用更频繁。
