Abstract
AgI-anatase TiO2 nanoparticle composites, (x)AgI-(1 â x)anatase, with different porosities were fabricated over a wide range of 0-1 of AgI content. The electrical conductivity was measured at room temperature as function of AgI content (x) and porosity (p). The conductivity varies considerably with both x and p. In the vicinity of x = 0.4 and p = 0.31, the conductivity attains a maximum (2.5 Ã 10â 3 S/cm). The conductivity is enhanced by three orders of magnitude in comparison with that of pristine AgI. The mechanism of the observed conductivity enhancement is discussed in the light of the scanning electron microscope images and X-ray diffraction patterns of the different (x)AgI-(1 â x)anatase composites.
