文摘

An exfoliation/restacking synthesis route has been developed for the fabrication of Ni–Al layered double hydroxide (LDH) intercalated Cu(II) tetrasulfophthalocyanine (CuPcs) hybrid by using exfoliated LDH nanosheets and guest molecules as building blocks. The structural and morphological features of the resulting hybrid have been investigated by varieties of analytical techniques such as XRD, SEM, UV–Vis and thermal analysis. Interlayer spacings determined from XRD patterns reveal a perpendicular orientation of the CuPcs macrocycles to the Ni–Al LDH layer. Then the obtained nanohybrid was utilized as photocatalyst for the decolorization of Rhodamine 6G (Rh6G) aqueous solutions. The effects of H₂O₂, time, substrate concentration, catalyst dose, were studied as a function of percentage of decolorization under irradiation and the corresponding dark controls were also carried out for comparison. The decolorization percentage of Rh6G increases with irradiation time and can reach to 70% at 6 h as against to 18% in dark control.
