Abstract
Abstract
In this paper, we present the synthesis, characterization, catalytic and
computational studies of Composites of Platinum-Iridium Alloy Nanoparticles and
Graphene Oxide (PtIr@GO) for dimethylamine borane (DMAB) dehydrogenation. The
prepared PtIr@GO nanocatalysts were synthesized using an ethanol super-hydride
method, and the characterization procedures for PtIr@GO alloy nanoparticles were
carried out by various advanced spectroscopic methods like X-ray Diffraction (XRD),
X-ray photoelectron spectroscopy (XPS), Transmission Electron Microscopy(TEM) and
high-resolution transmission electron microscopy (HRTEM). Additionally, catalytic
activity, reusability, substrate concentration, and catalyst concentration
experiments were performed for DMAB dehydrogenation catalyzed by PtIr@GO alloy
nanomaterials. According to the results obtained in this study, PtIr@GO NPs catalyst
was found to be active and reusable for the DMAB even at ambient conditions.
Besides, DFT-B3LYP calculations have been utilized on PtIr@GO cluster to reveal the
prepared catalyst activity. The calculated findings based on DFT was found to be a
good agreement with experimental results.
