abstract:
In order to study the effect of Mg 69 Ni 15 Gd 10 Ag 6 amorphous alloy on the photocatalytic degradation efficiency of methyl violet dye,UV-visible spectroscopy was were used to calculate the concentration variation during the photocatalytic degradation process.XRD and SEM were used to analyze the structural and morphological variation of crystal alloys and amorphous alloys before and after the photocatalytic degradation reaction,respectively.The results show that amorphous alloys exhibited higher efficiency for photocatalytic degradation of methyl violet dye than crystal alloy.The photocatalytic degradation efficiency of amorphous alloys reached 97.6%and 99.1%in 10 and 30 min respectively,while crystal alloys reached 63.3%and 74.5%in 10 and 30 min respectively.Thie superior photocatalytic degradation properties of Mg 69 Ni 15 Gd 10 Ag 6 amorphous alloys revealed a great potential for wastewater treatment.The photocatalytic degradation process of Mg 69 Ni 15 Gd 10 Ag 6 amorphous alloy to wards methyl violet dye is that the hydroxylation of central carbon atom occurs at first,and then the carbon-carbon bond of the central carbon atom breaks to form benzophenone.
