The invariance of the density of states (DOS) under varying pressures (0, 0.1333, 0.26667, and 0.4 Pa) (Figure ) indicates that the electronic structure of Pt-doped graphene remains stable across this pressure range. This stability suggests that the applied pressures have no significant effect on the electronic band structure, preserving the material's electrical properties. The consistent DOS implies that the conductive behavior, charge carrier density, and energy levels available for electronic transitions are unaffected, maintaining the material's suitability for applications in catalysis and electronic devices. Such pressure resilience highlights the robustness of Pt-doped graphene's electronic configuration, ensuring its performance in varying environmental conditions, including those involving mechanical stress or compression. This characteristic is particularly advantageous for oxygen evolution reactions (OER), where consistent electronic properties are critical for effective charge transfer and catalytic activity.
