Ultrasound assisted rapid synthesis of Pd/PdO binary nanorod alloy as hydrogen storage enhancer for GO-Pd/PdO nanocomposite

Abstract

This study focused on the synthesis and characterization of Pd/PdO nanoalloy and GO-Pd/PdO nanocomposites for potential applications in hydrogen storage. The Pd/PdO nanocomposite was prepared using a unique approach, utilizing the complex [Pd(DMB)₂] as both the precursor and dispersant. FTIR, XRD, SEM, EDX, and TEM, were employed to analyze the structural and morphological properties of the nanocomposites. The characterization results demonstrating the successful incorporation of palladium/palladium oxide nanoparticles onto graphene oxide sheets. Importantly, the hydrogen storage capacity of the nanocomposites was evaluated, with significant enhancements observed in the Pd/PdO nanomixture and the GO-Pd/PdO composite, indicating their potential as promising materials for hydrogen storage. This study provides valuable insights into the synthesis, characterization, and hydrogen storage properties of Pd/PdO and GO-Pd/PdO nanocomposites, contributing to the development of efficient and cost-effective hydrogen storage materials.
