Synthesis of hybrid Cu nanoflowers by using Tornabea scutellifera lichen extract, and evaluation of their dye degredation, and antioxidant activities

OpenAlex İngilizce

In this study, it was aimed to obtain Cu based organic@inorganic hybrid nanoflowers (Cu-hNFs) cheaply and effectively by using Tornabea scutellifera lichen extract as the organic component instead of expensive biomolecules such as DNA and enzymes. The effects of lichen extract concentration and pH of PBS buffer on the morphology of Cu-hNFs synthesized by the coordination of T. scutellifera lichen extract and Cu+2 were examined. It has been determined that Cu-hNFs did not synthesized under the pH ≤5 and, pH> 9 conditions of the PBS. Different morphological structures of Cu-hNFs synthesized under the pH 7.4 and, 9 conditions of PBS have been identified. In addition, it has been observed that the extract concentration used as an organic component has a significant effect on the morphology of Cu-hNFs. It has been recorded that synthesized Cu-hNFs have antioxidant activity against DPPH (IC50 = 0.98 mg/ml, R² = 0.9834). In addition, catalytic activity was demonstrated depend on pH of PBS and, concentration of Cu-hNFs against methylene blue and brillant blue. It is thought that these research data will be a guide for the synthesis and application potentials of various nanomaterials with T. scutellifera extract.
