I think bamboo itself likely lacks inherent photocatalytic activity for degrading textile wastewater pollutants (e.g., dyes). However, incorporating transition metals such as Ti, Zn, or Mo could functionalize it as an effective photocatalyst. For further insight, I recommend reviewing the following literature.
