Hierarchical Assembly of TiO2 Nanoparticles on WS2 Nanotubes Achieved Through Multifunctional Polymeric Ligands

Particles on the tube: Here, novel surface functionalization of WS2 nanotubes with polymeric ligands, by complexation with a combination of Ni2+ through a scorpionate-type nitrilotriacetic acid, and immobilization of TiO2 nanoparticles onto the surface of nanotubes is demonstrated (see schematic representation). The synthesis of the functional polymeric ligands was achieved through a reactive polymer precursor route.
