In terms of thermodynamic properties, the overpotential directly impacts the entropy and enthalpy of the system. A lower overpotential, like 0.300 V, typically correlates with a more favorable entropy change during the reaction, as it implies less energy is wasted, leading to a more efficient process. The enthalpy of the reaction might also be slightly lowered, as the platinum active sites provide a better match for the reactants' electronic configurations, reducing the activation energy. In turn, the reaction proceeds more spontaneously, and the overall efficiency improves. The favorable thermodynamic conditions ensure that platinum-doped graphene can effectively catalyze electrophilic reactions, balancing the entropic and enthalpic contributions to promote the desired transformation with minimal energy loss.
