Novel organic-inorganic nanohybrid (Pd-GO) nanocomposite: Sonochemical synthesis, characterization, and gas storage

Abstract

In this study, nanostructures palladium was synthesized using an ultrasonic wave which is innovative, expeditious, and ecologically benign protocol. In the procedure, ultrasonic probe with 150 W was applied to an aqueous solution of Na₂PdCl₄ containing sodium citrate for 1 h at room temperature. The as-prepared palladium nanoparticles were characterized through deployment of XRD, TEM, EDX, and UV-Vis techniques. Moreover, the study extends to take the benefits from palladium nanoparticles to produce a novel carbon-based composite using graphene oxide (Pd-GO) which was characterized by XRD, TEM, EDX, and UV-Vis. The organic-inorganic nanohybrid (Pd-GO) was then applied in a systematic investigation aimed at assessing its ability to enhance the hydrogen storage properties of GO as nano-palladium was incorporated at a ratio of 1 Pd: 100 GO, yielding a significant enhancement (48%) in the storage capabilities of pure GO.
