Article Synopsis
  • The study investigates platinum group metal-free (PGM-free) catalysts, focusing on iron-nitrogen-carbon (Fe-N-C) nanomaterials synthesized through a sacrificial support method (SSM).
  • By using various advanced techniques like X-ray spectroscopy and electron microscopy, researchers analyzed how different compositions and structures of these catalysts affect their performance in generating hydrogen peroxide (HO₂).
  • Findings reveal that Fe metallic particles play a crucial role in enhancing HO₂ production and that the active sites' characteristics significantly influence the catalysts' electrocatalytic activity.

We compare the electronic properties of Cu(111) and Cu(2)O(111) surfaces in relation to the dissociation of NO using first principles calculations within density functional theory. We note a well-defined three-fold site on both O- and Cu-terminated Cu(2)O surfaces which is verified as the active site for the adsorption and dissociation of NO. The interaction of Cu with O atoms results in the forward shifting of the local density of states and formation of unoccupied states above the Fermi level, compared to the fully occupied d band of pure Cu.
