Estimating the term…
A photocatalytic active carbon capable of demonstrating a stable deodorizing and adsorbing ability for a prolonged period of time is produced by depositing a coating of a photocatalyst on the surface of the active carbon by means of vapor deposition. Colored photocatalytic active carbon coloring active carbon including the photocatalytic active carbon, which while maintaining the adsorbing action and the decomposing and sterilizing action, comes to be rich in color variations and capable of improving visual design and handling are produced by subjecting the surface of the active carbon to coloring treatment and/or treatment with a compound having coloring or discoloring properties upon hydration.
A photocatalytic active carbon comprising active carbon and a coating of a photocatalyst formed by means of vapor deposition on a surface of the active carbon and a photocatalytic active carbon having been subjected to a coloring treatment comprising directly depositing a coating of a dye or pigment on the photocatalytic active carbon by means of vapor deposition.
A coloring photocatalytic active carbon comprising a photocatalytic active carbon comprising active carbon, a coating of photocatalyst formed by means of vapor deposition on a surface of the active carbon, and a compound having coloring or discoloring properties upon hydration carried on a surface of the photocatalytic active carbon.
A coloring photocatalytic active carbon comprising a colored photocatalytic active carbon and a compound having coloring or discoloring properties upon hydration carried on a surface of the colored photocatalytic active carbon, the colored photocatalytic active carbon comprising active carbon and coating of a photocatalyst formed by means of vapor deposition on surface of the active carbon.
