摘要: 采用飞秒激光辐照Fe颗粒制备了一种新型可见光水分解催化Fe纳米晶体系。悬浮在蒸馏水和NaCl溶液中的Fe纳米晶在可见光的辐照下实现了完全的水分解。利用气相色谱仪和扫描电子显微镜分析了Fe纳米晶材料可见光光催化储氢特性。结果表明:可见光辐照光催化后,Fe纳米晶表面出现块状和丝状结晶物。Abstract: A visible-light water-splitting photocatalyst was prepared by femtosecond laser: Fe nanocrystal. Both Fe nanocrystal suspended in distilled water and NaCl solution achieves total water splitting. The photocatalytic characteristics of Fe nanocrystal were analyzed by the gas chromatograph and scanning electron micrograph (SEM). Results show that the silk-like and bulk crystals appear on the surface of Fe nanocrystal after photocatalysis.
