| 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. |
