Process for producing crystalline titanium oxide coating film through electrolytic anodizing |
| abstract |
The invention concerns a method for producing a crystalline titanium oxide film useful as a photocatalyst, a photovoltaic element, etc. The crystalline titanium oxide film is produced by steps (a-1) and (b): (a-1) a step of heating titanium or titanium alloy under conditions (1) or (2) to form titanium nitride on the surface of the titanium or titanium alloy; (1) in an atmosphere of nitrogen and/or ammonia gas in the presence of a carbon material acting as an oxygen trapping agent; or (2) in an atmosphere where a pressure is reduced to discharge atmospheric gas, and then nitrogen and/or ammonia gas are/is introduced in the presence of a carbon material acting as an oxygen trapping agent; and (b) a step of immersing the titanium or titanium alloy obtained in step (a-1) above in an electrolyte containing an inorganic acid and/or organic acid, and applying voltage for anodization. |
