Polypeptide and copper oxide nanocomposite hydrogel for toxicity elimination of wastewater

Recent developments in hydrogels containing copper and palladium for the catalytic reduction/degradation of organic pollutants

“…In 2020, a new bionanocomposite of gelatin as a polypeptide hydrogel comprised of CuO nanomaterial (GL–CuO) was synthesized by Ahmad and co-workers. 91 After their dispersal, the synthesized CuO NPs were cross-linked with the addition of a CH 2 O solution in the GL aqueous solution. The synthesized GL–CuO with an average size of about 60–80 nm showed durable and extraordinary activity for the reduction of Congo red (CR) and methyl orange (MO) in an eco-friendly medium ( Scheme 11 ).…”
