titleOfInvention | A light-controlled sustained-release dual-network hydrogel catalyst for efficient reduction of Cr(VI) |
abstract | The invention discloses a light-controlled slow-release double-network hydrogel catalyst for efficiently reducing Cr(VI), which belongs to the field of environmental functional materials. In the present invention, acrylic acid is used as monomer, polyacrylate hydrogel is prepared by free radical polymerization method, and then placed in Fe(III) solution to utilize the coordination of iron and carboxylate to construct double-network hydrogel. The bulk-metal charge transfer mechanism slows the release of Fe(II) catalytic sites for Cr(VI) reduction. The hydrogel catalyst of the invention has the advantages of simple preparation process, strong stability, easy separation and reuse, and light-controlled sustained release with high efficiency and low consumption, and has broad application prospects. |
