TITANIUM OXIDE PRODUCTION METHOD, TITANIUM OXIDE, PHOTOCATALYST, AND PHOTOELECTRODE OF DYE-SENSITIZED SOLAR CELL

摘要

PROBLEM TO BE SOLVED: To provide a production method by which titanium oxide having a higher activity photocatalytic function can be obtained by a CVD method suitable for microparticulation.SOLUTION: The titanium oxide having a high activity photocatalytic function is produced by a flow including a vaporization process P1 for vaporizing a diol 1 and a titanium alkoxide 2, a precursor forming process P2 for forming a titanium oxide precursor 35 by reacting vaporized diol 13 and titanium alkoxide 24 in a vapor phase, and a heat treatment process P3 for obtaining anatase type titanium oxide 50 by heat treating the formed titanium oxide precursor 35.
