However, CuS NPs are easy to agglomerate in their preparation on account of the high surface activity. In this study, uniform dispersion of CuS NPs were fabricated with corn stalk as a template and stabilizer, further CuS@corn stalk\/chitin composite hydrogel was obtained by crosslinking with chitin. The results reveal that the CuS NPs were evenly dispersed into the composite hydrogels with a three-dimensional network structure, which were verified by the UV-vis spectrum, XRD, FT-IR spectra and SEM. In addition, the as-prepared composite hydrogel with the traits of peroxidase-like activity can convert H2O2 into an extremely oxidative and toxic \u00b7OH, which manifested good effects for photodegradation of RhB and antibacterial against Escherichia coli and Staphylococcus aureus. Hence, the composite hydrogels could be used for photocatalytic treatment and sterilization of wastewater, which provides a new idea for the functional application of CuS NPs.<\/jats:p>","DOI":"10.3390\/polym11091393","type":"journal-article","created":{"date-parts":[[2019,8,26]],"date-time":"2019-08-26T04:38:23Z","timestamp":1566794303000},"page":"1393","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["CuS@Corn Stalk\/Chitin Composite Hydrogel for Photodegradation and Antibacterial"],"prefix":"10.3390","volume":"11","author":[{"given":"Yutong","family":"Xiong","sequence":"first","affiliation":[{"name":"State Key Laboratory of Pulp and Paper Engineering, South China University of Technology, 381 Wushan Road, Guangzhou 510640, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bichong","family":"Luo","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Pulp and Paper Engineering, South China University of Technology, 381 Wushan Road, Guangzhou 510640, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guixin","family":"Chen","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Pulp and Paper Engineering, South China University of Technology, 381 Wushan Road, Guangzhou 510640, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jihai","family":"Cai","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Pulp and Paper Engineering, South China University of Technology, 381 Wushan Road, Guangzhou 510640, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qimeng","family":"Jiang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Pulp and Paper Engineering, South China University of Technology, 381 Wushan Road, Guangzhou 510640, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bin","family":"Gu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Pulp and Paper Engineering, South China University of Technology, 381 Wushan Road, Guangzhou 510640, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9303-6509","authenticated-orcid":false,"given":"Xiaoying","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Pulp and Paper Engineering, South China University of Technology, 381 Wushan Road, Guangzhou 510640, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,8,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"631","DOI":"10.1002\/smll.201301174","article-title":"Synthesis and Biomedical Applications of Copper Sulfide Nanoparticles: From Sensors to Theranostics","volume":"10","author":"Goel","year":"2014","journal-title":"Small"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1161","DOI":"10.2217\/nnm.10.85","article-title":"Copper sulfide nanoparticles for photothermal ablation of tumor cells","volume":"5","author":"Li","year":"2010","journal-title":"Nanomed.
