Abstract

Bacterial cellulose (BC) was chosen as carrier of nanometer titanium dioxide due to its superfine network structure. BC/titanium dioxide composite membrane was prepared by a sol–gel method using tetraisopropyl titanate as starting material. Photocatalytic properties of composite membrane were studied using methyl orange as degradation agent. Titania nanoparticles were successfully loaded on bacterial cellulose membrane. The degradation rate of methyl orange solution was up to 100% under ultraviolet (UV) irradiation. [ABSTRACT FROM AUTHOR]
