Bio-template Route for the Facile Fabrication of TiO2@Bacillus subtilis Composite Particles and Their Application for the Degradation of Rhodamine B

摘要

The Bacillus subtilis was used to synthesize the TiO2@Bacillus subtilis composite particles via a single-step strategy based on electrostatic interaction driving self-assembling heterocoagulation. Such materials had a rod-shaped microstructure with uniform size (1.4 +/- A 0.1 mu m in length; 450 +/- A 50 nm in width), and the removal ratio of rhodamine B was approximately 89 %.
