AgI–anatase TiO2 nanoparticle composites, (x)AgI–(1−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 x 10−3S/cm). The

conductivity was enhanced by three orders of magnitude in comparison with that of

pristine AgI. The mechanism of the observed conductivity enhancement was

discussed in the light of the scanning electron microscope images and X-ray

diffraction patterns of the different (x)AgI–(1−x) anatase composites.
