Design of ternary CeO2/Fe2O3/reduced graphene oxide-based hybrid nanocomposite for superior photocatalytic degradation material for organic dyes

Green energy and environmental preservation are becoming two foremost concerns in the human society. A successful strategy for addressing the issue of environmental pollution the photocatalytic application was helped to breakdown the harmful substances and sterilization of microorganisms in the presence of catalyst and sunlight. Herein, we introduced a serious of ternary CeO2/Fe2O3/r-GO based hybrid nanocomposite as an efficient catalyst for dye-degradation process. The effective catalyst was prepared via simple hydrothermal method assisted with annealing route. The hybrid catalyst was subjected to the XRD, FTIR, SEM and UV-DRS to estimate the structural and optical properties. Based on the study, the hybrid CeO2/Fe2O3/r-GO nanocomposite was exposed the brilliant absorption characteristics phenomena, and photocatalytic activities with remarkable stability. The methylene blue and methylene orange dye degradation activities were estimated using with the prepared hybrid nanocomposite. Fascinatingly, the hybrid CeO2/Fe2O3/r-GO catalyst was delivered the 90% and 86% dye-degradation result in the methylene blue and orange dyes under the UV light irradiation. Additionally, CeO2/Fe2O3/r-GO composite was gratefully recycled for five photodegradation sequences without experiencing any substantial changes to its activity or crystalline characteristics. The improved photocatalytic activity of the CeO2/Fe2O3/r-GO catalyst was mainly permitted to the synergic effects of the heterojunctions in the interface. The study's goal is to provide a good understanding for designing a suitable visible-light-driven photocatalyst with acceptable environmental remediation.
