摘要：

Diatom microalgae and their fossil Diatomaceous Earth (DE) are an abundant source of mesoporous silica, acting as a low-cost natural nanotextured material. Here we report a straightforward coating method of DE with polydopamine (PDA), an adhesive biocompatible organic polymer that is spontaneously generated by oxidative polymerization of dopamine in mild basic aqueous conditions. The resulting PDA-DE is expected to be a promising porous material for environmental remediation of seawater since it interacts with phenolic species used as model pollutants, enabling their removal from aqueous media.
