Photodegradation behaviour of sol–gel synthesized Bi4Ti3O12 for water pollution disinfection

Abstract

Minimization of water consumption and effective recycling of water by choosing the appropriate water treatment technique in industry are the most essential in this modern era. Nowadays, the usage of sol–gel synthesized nanomaterial to study the photo degradation behavior of disinfected water pollution is a promising way. Phase purity analysis, reusability test, photoarate constant of photo-catalytic and rate constant of photolysis reaction were examined. X-ray diffraction (XRD) results confirm the formation of Bi4Ti3O12 (BTO) with an orthorhombic structure. The phase purity of the catalyst is also analyzed using the Jana2006 refinement. The FESEM image revealed a hexagonally structured particle with an indistinguishable grain boundary. The degradation behaviour of Rhodamine-B (RhB) in sunlight is investigated under the influence of BTO nanoparticles. The rate constant of the photo-catalytic and photolysis reaction is found to be 0.0198 and 0.0008. Degradation efficiencies are found to be 91.3% for RhB. Overall results revealed that the sol–gel synthesized bismuth titanium oxide (Bi4Ti3O12) is best choice for water pollution disinfection.
