Using a simple sol–gel method, a novel magnetic photocatalyst was produced by immobilization of TiO 2 nano-crystal on Fe-filled carbon nanocapsules (Fe-CNC). High resolution TEM images indicated that the immobilization of TiO 2 on Fe-CNC was driven primarily by heterogeneous coagulation, whereas surface nucleation and growth was the dominant mechanism for immobilizing TiO 2 ...
In this work, TiO 2 nanoparticles were immobilized on the carbon nanocapsules (CNC) treated by H 2 SO 4 /KMnO 4 using a sol-gel process. The TEM images of the TiO 2 -coated CNC suggested that introducing crystallographic defects by acid functional groups tended to facilitate TiO 2 immobilization onto the nanocapsules. The TiO 2 -coated CNC exhibited...
