Bi-modal porous structured TiO_2-ZrO_2 composites were developed on glass substrates using dip coating technique. Porosity and reduction in particle agglomeration were achieved through the incorporation of Pluronic F127. Porous nature of the film was studied using field emission scanning electron microscopy (FE-SEM) and structure formation was investigated by high angle annular dark field (HAADF) images. Raman imaging and elemental mapping revealed the presence of Ti, Zr and O elements Photo-induced hydrophilic self-cleaning property (dye degradation) was observed for both double templated and UV irradiated samples. A feasible mechanism has been evolved to explain the retainability of hydrophilic nature of the films.
