合成了具有增强光催化氧化活性的金属玻璃/二氧化钛(MG/TiO 2)粉体,并将其应用于亚甲基蓝(MB)溶液的脱色。与相同条件下的纯TiO 2和晶态合金/TiO 2(CA/TiO 2)相比,其降解率分别提高了60%和30%。与CA/TiO 2相比,MG/TiO 2光催化降解MB的速率提高了3倍。这些新型粉体在可见光照射下具有优异的光催化降解性能,在水净化领域具有潜在的应用前景。
The metallic glass/titanium dioxide powders (MG/TiO2) with enhanced photocatalytic oxidation activity were synthesized, which exhibit a higher efficiency in decolorizing methylene blue solutions (MB). Compared with the pure TiO2and crystalline alloy/TiO2(CA/TiO2) under the same circumstances, its degradation rate was 60 % and 30 % higher, respectively. Furthermore, compared with the CA/TiO2, the MG/TiO2photocatalytic rate was three times faster when decolorizing MB. Considering the excellent intrinsic high-performance photocatalytic degradation under visible light irradiation, these novel powders were proven to have potential applications in water purification industry.
