Description:
Pure and carbon nanotube (CNT) attached BiFeO 3 and Bi 2 Fe 4 O 9 were prepared via hydrothermal route at fixed temperature, with time and mineralizer as variants. Phase purity of products was determined through X-ray diffraction (XRD) studies. FESEM analyses revealed that synthesized materials exhibited various morphologies, depending on the mineralizer being employed in the synthesis. Optical band gap measurements have been carried out using UV-Vis spectroscopy analyses. The attachment of CNT reduces the bandgap, and consequently enhances photocatalytic activity due to the electron transfer from BiFeO 3 to CNT. The pseudo-first order model of reaction kinetics has been used successfully to study the associated mechanism.
