Copper sulfide nanoparticles (CuS NPs) have recently attracted extensive attention in various fields due to their excellent optical and electrical properties. However, CuS NPs are easy agglomerate preparation on account of the high surface activity. In this study, uniform dispersion were fabricated with corn stalk as a template stabilizer, further CuS@corn stalk/chitin composite hydrogel was obtained by crosslinking chitin. The results reveal that evenly dispersed into hydrogels three-dimensional network structure, which verified UV-vis spectrum, XRD, FT-IR spectra SEM. addition, as-prepared traits peroxidase-like activity can convert H2O2 an extremely oxidative toxic ·OH, manifested good effects for photodegradation RhB antibacterial against Escherichia coli Staphylococcus aureus. Hence, could be used photocatalytic treatment sterilization wastewater, provides new idea functional application NPs.
