The BiOBr/regenerated cellulose composite film as a green catalyst for light degradation of phenol

• The BiOBr/RC has been prepared via in-situ synthesis method.
• The influence of the porous cellulose film to the BiOBr photodegradation of phenol was investigated.
• The BiOBr/RC exhibited good photocatalytic activity for the photodegradation of phenol.
• The BiOBr/RC is a portable catalyst.

A portable catalyst, BiOBr/regenerated cellulose composite films (BiOBr/RC), was prepared for the application of photocatalytic irradiation under visible light. It exhibited good photocatalytic activity for the photodegradation of phenol which means it has potential for the application in photodegradation of organic pollutant. Cellulosic biomass is a kind of green material, and the composite film is easy to recycle and has good reproducibility. So it's a “green” processing for the catalyst can be removed easily from pollution solution after being used and to be used for the next run.
