Abstract
Implementing nanosized materials (1–100 nm) are considered to be effective approaches in addressing the issue of liquid waste pollution. Herein, ZnO-carbon quantum dots (ZnO-Cdots) were conducted by three-steps hydrothermal synthesis and the structural characterization is confirmed by the physical properties measurement, while, photodegradation activity of ZnO-Cdots compared to the prepared ZnO nanoflower have been investigated using UV–visible absorbance spectroscopy and its effect on organic pollutant removal from aqueous. The obtained ZnO-Cdots composites showed a superior performance in photocatalytic degradation of methylene blue (MB) and specific antibacterial activity against Staphylococcus aureus (S.A) and Eschericia coli (E.coli) compared with the prepared ZnO nanoflower. The findings of this research of ZnO-Cdots show great potential in treating liquid waste pollution, and can be considered as a promising antibacterial agent for Staphylococcus aureus (S.A) and Eschericia coli (E.coli).
