The antibacterial ability of nCu-MWCNTs combined with H2O2 was evaluated.
nCu-MWCNTs/H2O2 exhibited superior antibacterial effect against E. coli.
Synergistic interaction happened between nano-Cu, MWCNTs and H2O2.
MWCNTs promoted the electron transfer of nano-Cu and promoted the generation of OH.
Copper ions and OH contributed the deactivation ability.
