Nanoporous TiO 2 developed from two templates for their use in photovoltaic applications

Described work is a development of templated nanoporous TiO 2 using two different substrates. Controlled parametric syntheses of nanoporous textures give rise high surface area as well as high aspect ratios. High electric field application for specific time and the composition of electrolytes used i...

Controlled parametric syntheses of nanoporous textures give rise high surface area as well as high aspect ratios. High electric field application for specific time and the composition of electrolytes used in synthesis cell needs a careful study.

Ti templated and Ti-Al templated nanoporous TiO 2 shows lower porosity at low voltage treatments, while both the templates reveal high porous structure at 20V. Increasing the time of Ti template for a specific voltage leads to collapse of pores while it enhances the roughness of the walls of collapsed pores and hence improving the surface rea.
