Preparation of a stable polyurethane sponge supported Sn-doped ZnO composite via double-template-regulated bionic mineralization for visible-light-driven photocatalytic degradation of tetracycline

A new tin-doped zinc [email protected] polyurethane ([email protected]/PU) composite photocatalyst was prepared by in-situ growth of tin-doped zinc oxide (Sn-ZnO) on the surface of polydopamine-modified polyurethane (PDA/PU) via double-template-regulated bionic mineralization strategy. The flake-like Sn-ZnO regulated by soft template (sodium citrate) contributed to outstanding photocatalytic activity of [email protected]/PU composite. In...
