Description
Summary:Currently, the preparation of novel efficient and recyclable photocatalysts for pollutant degradation in water has become a research hotpot. In this study, a TiO 2 -loaded non-woven polypropylene/bacterial cellulose (TiO 2 -loaded NPBC) composite film was prepared by a biological culturing method. The TiO 2 nanoparticles were spontaneously embedded into the prepared composite film. Then, the composite film was used to degrade methylene blue (MB) and its degradation effects were explored. The morphology of the composite film was investigated. It was clear that a large amount of TiO 2 nanoparticles were embedded into the composite membrane during the biological culturing method. The experimental results confirmed that the TiO 2 -loaded NPBC composite film had good degradation performance and reusability. When the reaction time was 120 min, the removal rate of MB by the film was 92.8 %. The removal rate remained above 85 % after 5 degradation cycles.
