3D-Nanosponge enabled segregation: a versatile approach for highly dispersed and high content functionalization of metal oxide species

摘要: Nanomaterials functionalized with metal oxide species have aroused broad research interest in biomedical, catalysis and adsorption applications. However, a generalized functionalization approach achieving both high dispersity content of is rarely reported. In this study, novel three-dimensional nanosponge (3D-NS) enabled strategy developed to tackle challenge. Instead directly modifying onto nanoparticles as performed conventional approaches, the “empty” pores are creatively converted into “sponge-like” 3D nanospace by filling up resoles rich anchors, which efficiently accommodate maintain their highly dispersed state during fabrication process. This generic achieve different single binary compositions. As demonstration, copper derived from show excellent Fenton-like catalytic activity enhanced cancer cell inhibition performance. These findings provide new understanding useful tools for development nanomaterials advanced
