TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Catalyst: The mean diameter of the platinum particles is 1-10 nm. The amorphous metal oxide is selected from titanium oxide (TiO2), nickel oxide (NiO), tin oxide (SnO2) and/or zinc oxide (ZnO). The catalyst (C1) comprises platinum particles (50-200 parts by weight (pbw)). The metal oxide precursor is titanium isopropoxide, titanium methoxide, or titanium ethoxide. The platinum precursor is selected from H2PtCl6, H2PtCl4 and/or (Pt(NH3)4)Cl2. The catalyst has x-ray diffraction pattern as given in the specification.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The block copolymers are selected from poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) block copolymer, and/or poly(propylene oxide)-poly(ethylene oxide)-poly(propylene oxide) (PPO-PEO-PPO) block copolymer. Preferred Method: The heat-treating is performed at 400-500 degrees C. EXAMPLE - A solution of (poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol) (P123)/acetyl acetone (ACA) was obtained by dissolving P123 (poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol) (PEO20-PPO70-PEO20) (molecular weight (Mw)=5750) (5 g), in acetyl acetone (ACA) (40 g). Additionally, a titanium isopropoxide/acetyl acetone (TTIP/ACA) solution was obtained by dissolving TTIP (7.1 g) in ACA (10 g). The molarity of the TTIP/ACA solution was 0.072 M. The TTIP/ACA solution was drop-added to the P123/ACA solution, and the resulting solution was agitated for 12 hours, to obtain a transparent yellow solution. H2PtCl6 (0.1 mol/l), which was the platinum precursor, was added to the resulting solution, to obtain a template polymer solution containing a titanium (Ti) precursor. The template polymer solution containing Ti precursor was spin-coated on an indium-tin-oxide (ITO) conductive substrate at 2000 revolution per minute (rpm) for 20 seconds. Next, the resulting material was heat-treated at 450 degrees C for 30 minutes, to form a platinum-titanium oxide (TiO2) electrode, which was used as a second electrode. A dispersed solution of titanium oxide particles, each having a diameter of 30 nm was applied on 1 cm2 of an ITO film of a first electrode. The applied solution was heat-treated at 450 degrees C for 30 minutes by forming a porous layer having a thickness of 15 mu m. Next, the resulting material was maintained at 80 degrees C, and used as the dye (ruthenium-based dye N719), and then underwent a dye adsorption process for 12 hours, impregnated in 0.3 mM of a dispersed solution that was dissolved in ethanol. Then, the porous layer adsorbing the dye was washed out by ethanol, and dried at room temperature, to obtain a first electrode, on which a light absorption layer was formed. The second electrode was the platinum-titanium oxide (TiO2) electrode, and a fine hole having a diameter of 0.75 mm was formed through the second electrode, to inject the electrolyte. A support, formed of a polymer film having a thickness of 60 mu m, was disposed between the first electrode, on which the porous layer was formed, and the second electrode. The first and second electrodes were pressed, and adhered to each other. Next, the electrolyte was injected through the fine hole formed through the second electrode, and the fine hole was sealed by a glass cover and a thermoplastic polymer film, by completing the manufacture of a dye-sensitized solar cell. The electrolyte was prepared by dissolving 1-hexyl-2,3-dimethyl imidazolium iodide, lithium iodide (0.1 M), iodine (0.05 M), and 4-tert-butylpyridine (0.5 M), in 3-methoxypropionitrile.
