Area of Science:

  • Materials Science
  • Nanotechnology
  • Chemistry

Background:

  • Hollow nanoparticles offer unique properties for various applications.
  • Understanding the internal composition and shell properties is crucial for controlled synthesis and application.
  • Iron oxide nanoparticles are of interest due to their magnetic and catalytic properties.

Purpose of the Study:

  • To investigate the internal composition of hollow gamma-iron oxide (γ-Fe(3)O(4)) nanoparticles.
  • To determine the nature of the void space within these nanoparticles.
  • To assess the impenetrability and porosity of the γ-Fe(3)O(4) shell.

Main Methods:

  • Synchrotron X-ray diffraction (XRD) and small-angle X-ray scattering (SAXS) were employed.
  • High-pressure experiments using a diamond anvil cell (DAC) with neon as a pressure-transmitting medium were conducted.
  • Fourier-transform infrared (FTIR) spectroscopy was used to analyze fragmented nanoparticles.

Main Results:

  • Small-angle X-ray scattering revealed a high electron density within the hollow void, suggesting the presence of dense material.
  • X-ray diffraction and FTIR analysis indicated that the γ-Fe(3)O(4) shell is non-porous and impenetrable to gases, liquids, and organic molecules.
  • High-pressure experiments confirmed pressure transmission to a gold core within core/shell nanoparticles, implying the void or gap is filled with a pressure-transmitting medium.

Conclusions:

  • The void inside the hollow γ-Fe(3)O(4) nanoparticles most likely contains small fragments of iron and/or iron oxide.
  • The synthesized iron oxide shells are robust, non-porous, and effectively seal the internal void.
  • These findings are critical for designing and utilizing hollow nanoparticles in applications requiring controlled internal environments.
