Porous “sponge-like” anatase TiO2 via polymer templates: synthesis, characterization, and performance as a light-scattering material
The synthesis of porous “sponge-like” TiO 2 via a polymer gel coating technique is presented. The experimental procedure involves the preparation of a gelled polymerizable microemulsion. The polymerization of the latter leads to porous poly- N -isopropylacrylamide which forms a hydrogel in the prese...

| description | The synthesis of porous “sponge-like” TiO
2
via a polymer gel coating technique is presented. The experimental procedure involves the preparation of a gelled polymerizable microemulsion. The polymerization of the latter leads to porous poly-
N
-isopropylacrylamide which forms a hydrogel in the presence of water. Via solvent exchange, a suitable TiO
2
precursor is infiltrated into this structure after which its in situ hydrolysis is triggered to form porous amorphous TiO
2
. The subsequent calcination step allows the removal of the polymer template and the transformation of amorphous TiO
2
into porous, crystalline anatase with domain sizes ranging from 200 to 250 nm. As a means of verification and proof of concept, this material is tested as light-scattering layer in dye-sensitized solar cells (DSSC), and it is found that the resulting solar cell performance is comparable to commercially available TiO
2
. However, an increased tendency to form rutile during DSSC fabrication was noticed when compared to commercial TiO
2
. As there is a large potential for optimizing the synthesis, the proposed procedure is a promising route towards porous TiO
2
that performs significantly better as scattering layer in light-harvesting and optical devices. |
