摘要

In this work, we have synthesized bamboo stem porous activated carbon/zinc oxide/copper oxide (BSPAC/ZnO/CuO) ternary nanocomposite using hydrothermal method. Subsequently, the synthesized BSPAC/ZnO/CuO ternary nanocomposite, BSPAC, ZnO and CuO NPs were confirmed by FT-IR, powder XRD, Raman, FE-SEM, EDAX with elemental mapping, UV–Vis DRS, HR-TEM, TGA, XPS and BET surface analysis. Following that, FT-IR and XRD analysis was provided the clear information about functional moieties and crystalline pattern of BSPAC, CuO, ZnO and BSPAC/ZnO/CuO ternary nanocomposite. The FE-SEM images of BSPAC was shown broken honey comb like structure whereas, after the fabrication of ternary nanocomposite provided spongy and rod like morphology with clustered aggregation. Then, the EDAX spectrum of BSPAC/ZnO/CuO was shown atomic weight% of carbon 27.27, oxygen 15.57, zinc 28.72 and copper 25.81 respectively. Further, HR-TEM images illustrated that spherical and rod morphology and their size was found to be 7–10 and 27–40 nm respectively. Moreover, the distinctive BET surface area of synthesized ternary nanocomposite was found to be 140.42 m²/g. The antibacterial activity of the ternary nanocomposite was tested against various Gram-positive and negative bacterial strains, and the excellent antibacterial activity was observed in B. subtilis (13.03 ± 0.08 mm), B. megaterium (14.00 ± 0.11 mm) and S. aureus (15.00 ± 0.11 mm) compared to Gram-negative bacterial strains. And also, the anticancer activity of HCT-116 cell line was shown significant outcome with IC50 value of 59.18 µg/mL after 24 h treatment. These research finding confirms that the synthesized ternary nanocomposite has new insight for the development of biomedical application.
