Abstract

Abstract: In this study, PdRu@GO catalyst was fabricated for hydrogen evolution from dimethylamine borane (DMAB). PdRu@GO catalyst was characterized by X-ray photoelectron spectroscopy (XPS), Transmission electron microscopy (TEM), High-resolution transmission electron microscopy (HR-TEM), X-ray diffraction spectroscopy (XRD), and Raman spectroscopy. The fabricated catalyst composed of a monodisperse distribution of palladium/ruthenium on graphene oxide and has a mean particle size of 2.74 ± 0.53 nm. The nanoparticles were tested in the catalytic reaction of DMAB at different parameters such as temperature, substrate/catalyst concentrations, and reusability. The test results performed with different parameters showed that PdRu@GO catalyst exhibits high catalytic performance in the dehydrogenation of DMAB under room conditions. PdRu@GO catalyst was determined to have 330.22 h −1 of TOF and 28.72 kJ mol −1 of activation energy (Ea) values for the catalytic dehydrogenation reaction of DMAB. Highlights: Highly efficient PdRu@GO nanocatalysts were synthesized via microwave-assisted method. PdRu@GO was utilized to catalytic dehydrogenation of DMAB. PdRu@GO has been reported as highly efficient, stable and durable catalyst. Synthesized nano catalyst exhibited significiant catalytic activity with a TOF value of 330.22 h −1, and Ea = 28.72 kJ mol −1 .
