Novel Approach for the Synthesis of Nanocrystalline Anatase Titania and Their Photovoltaic Application

الملخص EN

High surface area titania with crystalline anatase walls has been synthesized using ordered large mesoporous carbon as a template.

The pore structure of mesoporous carbon is infiltrated with titanium tetraisopropoxide solution at room temperature and the mixture is subjected to heat treatment at 550Co in presence of air to complete removal of the template.

The prepared crystalline anatase frameworks are characterized by XRD, N2 adsorption and HR-TEM.

The nitrogen adsorption-desorption analysis of the prepared anatase titania particles exhibits BET specific surface area of 28 m2/g.

The dye-sensitized solar cells performance of this anatase titania material has been tested and energy conversion efficiency of 3.0% is achieved under AM 1.5 sunlight.

This work reports a new approach for fabrication of nanocrystalline anatase titania by simple hard templating technique for the first time and their applications for dye-sensitized solar cell.
