From the Mulliken nucleophilic analysis, the platinum atom in the graphene structure exhibits consistent nucleophilic character across varying external pressures. This stability in electron-rich behavior highlights the robustness of the Pt nucleophilic center, which likely facilitates its interaction with electrophilic species. Additionally, the induced charges on carbon atoms C2, C6, and C8 demonstrate a localized redistribution of electron density around these sites. The nearly uniform charge values at these positions suggest a coordinated electronic response, further enhancing the reactivity and adsorption capabilities of the material. Such behavior aligns with the role of nucleophilic centers in improving the material's interaction with electron-deficient molecules, making platinum-doped graphene a promising candidate for catalytic and sensing applications under different pressure conditions.
