Regarding electron recombination, the charge distribution in the Pt-doped phenalene also plays a pivotal role in minimizing this detrimental effect. The higher positive charge on platinum creates an electron-deficient site that promotes charge separation upon excitation. This strong electrophilic character encourages the effective transfer of electrons from the adsorbate to the platinum center, reducing the likelihood of charge pair recombination. The bonding carbons (C3, C5, and C7), with their smaller partial charges, act as electron-rich centers that stabilize the electron density during the reaction. This stabilization, combined with the electrostatic interaction between the platinum and carbon atoms, prevents the recombination of electrons and holes, thereby enhancing the charge carrier lifetime. As a result, the Pt-doped phenalene maintains efficient electron flow, which is crucial for sustaining high catalytic activity and achieving long-term stability in electrochemical applications.
