Figure 3. FE-SEM images of the BiOCl-PT composite showing (a) a
typical composite particle and (b and c) magnified details of the
composite particles in which the highly porous character of the TiO2
material and the distribution and shape of the BiOCl nanoplates can
be appreciated. The arrows point to BiOCl nanoplates stacked to the
TiO2 network.
