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.
