Textile-Bound Copper Silicate as a New Peroxidase-Like Nanozyme for Organic Dye Decolorization

Copper silicate (CS) bound to a nonwoven textile was prepared using a very simple procedure employing water glass as a precursor and subsequent copper sulfate treatment. Peroxidase-like activity of the textile-based CS derivative was detected for the first time. This new nanozyme was employed for the decolorization of three model organic dyes: Bismarck brown Y, Congo red, and methylene blue. Both adsorption and peroxidase-like dye degradation were involved during the decolorization process.

Automated summary

A copper silicate nonwoven textile with peroxidase-like activity was synthesized using water glass and copper sulfate. This novel nanozyme was found to be capable of decolorizing organic dyes through both adsorption and peroxidase-like degradation.
