主　　题：Graphdiyne CuO/GDY nanocomposite Escherichia coli Antibacterial Superoxide radical 

摘      要：Copper oxide(CuO),due to its low cost,good chemical and physical stability,has recently been given special attention as a potential candidate for antibacterial ***,developing novel CuO nanocomposites with improved antibacterial property and unraveling the interface promotion mechanism has been a fundamental challenge for ***,well-defined CuO/graphdiyne(CuO/GDY)nanostructures with uniformly anchored CuO nanoparticles(ca.4.5 nm)have been *** CuO/GDY nanostructure exhibited superior *** inactivation efficiency,which is nearly 19 times and 7.9 times higher than the bare GDY and commercial CuO,*** improved *** inactivation performance was mainly due to the increased reactive·O_(2)−species generated by the activation of molecular O2 over CuO/GDY *** findings demonstrate the efficient antibacterial activity of well-defined CuO/GDY nanostructures and provide insights on the development of efficient GDY-based antibacterial materials.
