Addressing the ecological issues through sunlight-driven photocatalytic oxidation is a challenging and exciting theme. Therefore, different kinds of photo-active materials have been designed so far to tackle the problem of wastewater pollution. In this study, multilayered graphene with platelets morphology is integrated with CeO2 nanoparticles (NPs) to design GNPs/CeO2 (GNPs: CeO2 = 1:3, 1:1 and 3:1) nanocomposites (NCs) using ultrasonic method. The physical properties of CeO2 have been tuned by varying the loading content of GNPs. These NCs have been characterized for their physico-chemical properties, which confirmed the formation of the NCs with porous morphology, tuned bandgap and enhanced photocatalytic characteristics. The GNPs/CeO2 NCs have displayed considerably enhanced capability to decompose methylene blue as compared to the pristine CeO2 NPs. The improvement in photodegradation activity of the NC can be attributed to the tuned bandgap and effective transport of photoelectrons in the conducting channels provided by GNPs in the structure. GNPs/CeO2 NCs can be auspicious photocatalyst for industrial wastewater treatment. [ABSTRACT FROM AUTHOR] |
