Abstract

The stability of platinum-carbon nanoparticles (Pt-C NPs) under shock wave loading conditions is examined in this work to evaluate its possible use in aeronautical applications. Our analysis of the optical, structural, and compositional features of Pt-C NPs was conducted using X-Ray diffraction Spectroscopy (XRD), Scanning Electron Microscopy with energy-dispersive X-ray Spectroscopy (SEM-EDS), and Ultraviolet-Visible Diffuse Reflectance Spectroscopy (UV-DRS). No notable changes were noticed in the following parameters following shock wave exposure: absorbance spectra, band gap energies, surface morphology, microstrain, grain size, dislocation density, or reflectance profiles. These results demonstrate the strength of Pt-C NPs and prove that they are appropriate for demanding aerospace settings where dependability and longevity are critical.
