A TiO2 fi LM electrode (photoanode) was prepared by blending commercial TiO2 powder (Degussa P25), of Ca.0.2, G nitric solution (0.1 M) of 0.4 ml polyethylene glycol,,(MW10 000), of Ca. 0.08 g and one drop of a, nonionic surfactant Triton X-100. The mixture was well mixed using an ultrasonic. Bath for 1 h and then the resultant paste.Was spread over a conductive glass plate having 15 O = cm2.Which was purchased from Hartford Glass Co, Inc. The.Coated plate was then sintered at 450 C for 2 h. The dyes.Were attached to the TiO2 surface by immersing the coated.Electrodes in the aqueous solution of each dye for 24 h. The.Non-adsorbed dye was washed up with anhydrous ethanol.Pt counter electrode was prepared by deposition of Pt -.Catalyst T / SP paste (purchased from Solaronix SA on.)Another conductive glass.
