Abstract

Abstract: In this study, distilers' grains were used to prepare biochar, then cuprous oxides nanoparticles were firstly loaded to the biochar to improve the properties of Cu2 O. The characterizations of their structure and morphology show that the Cu2 O nanoparticles have been loaded onto the biochar successfully and the biochar-based Cu2 O nanoparticles (Cu2 O/biochar composites) have larger specific surface area than pure Cu2 O nanoparticles. Their antibacterial activity against Escherichia coli ( E. coli ) was examined. The results show that Cu2 O/biochar composites have superior antibacterial performance than pure Cu2 O nanoparticles which indicates that the existence of biochar can improve the antibacterial activity of Cu2 O nanoparticles.
