Summary:PURPOSE: A manufacturing method of integral nanotube photocatalyst reducing hexavalent chrominum, a hexavalent chrominum reducing device and a reducing method using the same are provided to adjust a rate of a crystalline form for Rutile structure and Anatase structure. CONSTITUTION: A manufacturing method of integral nanotube photocatalyst includes a step for forming an amorphous titanium oxide layer of a nanotube form on a titanium supporter by anodizing the surface of the titanium supporter for 30 ~ 120 minutes, and a step for deforming the titanium supporter to an titanium oxide layer which is formed with only Anatase structure or Anatase structure and Rutile structure.
