Abstract

BiFeO₃-Graphene-LiNbO₃ ternary nanocomposites has been synthesized using wet chemical method for the first time. The existence of ternary entities chosen for the preparation of composite matrix has been ascertained from the conventional analytical tools like XRD, SEM & TEM, XPS and Raman measurements. Addition of ABO₃ type dielectric materials namely BiFeO₃ and LiNbO₃ over graphene matrix found have improved the photocatalytic behaviour of synthesized ternary composites, especially in degrading methylene blue effluent within 120 min for the graphene loaded sample with a concentration of 0.025 and exhibits maximum degradation efficiency of 88 % over the other graphitic concentrations studied. Hence, this study indicates that the optimum concentration of graphene required for enhancing methylene blue dye degradation in similar intervals of time stands at 0.025 for BiFeO₃-Graphene-LiNbO₃ photocatalyst. The other studies substantiating the present conclusive evidence is also appended in this work.

期刊介绍： Sustainable Materials and Technologies (SM&T), an international, cross-disciplinary, fully open access journal published by Elsevier, focuses on original full-length research articles and reviews. It covers applied or fundamental science of nano-, micro-, meso-, and macro-scale aspects of materials and technologies for sustainable development. SM&T gives special attention to contributions that bridge the knowledge gap between materials and system designs.
