Recently, the produced nanoflowers by combining organic and inorganic structures are frequently studied in the literature. Usually, the inorganic and organic components are selected as Cu2+ ions and proteins, enzymes, and different combinations with various support materials, respectively. These materials are used in many fields such as enzyme activity, catalytic activities, analytical applications, etc. The nitrophenol compounds and organic dyes used in catalytic applications are a problem that is often encountered as water pollutants. In wastewater cleaning, removing these components from the environment is a problem in itself. Because nitrophenols and organic dyes have high stability in nature, they are difficult to degrade and reduce. Therefore, they must be reduced through catalytic processes. Similarly, they were tested as counter electrodes influencing the reduction reaction in DSSC devices [1-3].

We were fabricated new nanocomposites with carbon nanotube (CNT) supporting hybrid nanoflowers (CNT-Cu@Nanoflower). The characterizations of these CNT-Cu@Nanoflower nanocomposites were performed by scanning electron microscopy (SEM), Energy Dispersive X-Ray Analysis (EDX), Fourier Transform Infrared Spectroscopy (FT-IR), and X-ray Powder Diffraction (XRD). Then, the materials were used as catalysts for the reduction of 2-nitrophenol, 4-nitrophenol, Rhodamine B, and methylene blue compounds in the aqueous medium in the presence of NaBH4. In the monitoring of spectra belonging to reduced products was used with UV-vis spectrophotometer. Also, the fabricated CNT-Cu@Nanoflowers materials were tested as counter electrode in DSSC devices.
