| 摘要: |
Lepidocrocite was synthesized by aerial oxidation using an FeIIEDTA solution. The synthesis was performed
under irradiation from different monowavelength light emitting diode (LED) lamps at room
temperature. X-ray diffraction results showed the formation of differently crystallized lepidocrocite. The
indirect bandgap values of the lepidocrocite samples were about 2.34, 2.36, and 2.31 eV for red, green, and
blue light, respectively. The kinetics of the photo-decolorization of crystal violet (CV) was investigated
in a system composed of lepidocrocite, H2O2, and visible light. H2O2 concentration, light irradiation, and
catalyst concentration were also investigated. The rate of CV decolorization was found to fit pseudo-firstorder
kinetics. The results show that different as-prepared lepidocrocite have different adsorption and
photocatalytic characteristics. A possible mechanism was also suggested for the dye degradation. |
