To provide a photocatalytic activated carbon capable of exhibiting a stable adsorption/decomposition ability and deodorization/sterilization ability and soil cleaning ability for a long period of time, and to provide a colored photocatalytic activated carbon having improved visual designability and handling property while keeping the adsorption/decomposition ability and the deodorization/sterilization ability, color activated carbon, and a deodorant and/ adsorption product and soil cleaning method using them.

The photocatalytic activated carbon is formed by forming and supporting a thin film of a photocatalyst on the surface of activated carbon. The colored photocatalytic activated carbon is obtained by coloring the photocatalytic activated carbon. The coloring activated carbon is obtained by supporting a compound having a character coloring or discoloring by the hydration on the surface of the photocatalytic activated carbon or the colored photocatalytic activated carbon. The deodorant and/adsorption product and the soil cleaning method using them are provided.
