• Femtosecond laser ablation
• ZnSe nanosheets
• Photodegradation

ZnSe nanosheets have been fabricated by femtosecond laser ablation in distilled water at room temperature. Their crystal structure, crystal phase, shape and size distribution, and photophysical property are investigated using X-ray diffraction (XRD), Raman spectroscopy, field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), high resolution transmission electron microscopy (HRTEM) and UV-Vis spectroscopy. The as-prepared ZnSe nanosheets efficiently catalyze the photodegradation of methyl orange (MO) present in aqueous solutions under visible light irradiation, exhibiting higher photocatalytic activity than ZnSe microsized particles. The high photoactivity of the nanosheets can be attributed to the combined effects of large surface areas and the more unsaturated surface coordination sites exposed to the solution.
