Nanohybrids of Ultrathin Titania Nanosheets and Zinc Oxide Nanoparticles by an Electrostatic Interaction

We synthesized ultrathin titania nanosheets and zinc oxide nanoparticles, and formed the nanohybrids of them by an electrostatic interaction. The titania nanosheets were prepared by soft chemical processes: intercalation, exfoliation, and reassembly. The zinc oxide nanoparticles were prepared by the sol-gel method. And two nano-scale inorganic materials were hybridized to form nanohybrids using an electrostatic interaction as a driving force. According to the X-ray diffraction pattern and high-resolution transmission electron microscope images, it is revealed that the nanohybrid of the titania nanosheets and zinc oxide nanoparticles has a house of cards structure in which zinc oxide nanoparticles are randomly attached to layered titania nanosheets.
