Abstract Understanding how to tune the properties of electroactive materials is a key parameter for their applications in energy storage systems. This work presents comprehensive study tailoring polyaniline (PANI) suspensions by acid‐assisted polymerization method and subsequent deposition on boron‐doped diamond (BDD) supports with low/high B concentrations. The porous or densely packed morphology PANI successfully controlled varying monomer‐to‐initiator ratio. interaction between BDDs leads shift oxidation reduction potentials, high doping resulted potentials. Notably, highest specific capacitance 958 F g −1 , which represents 90% theoretical capacitance, recorded support relatively low content. Moreover, obtained slow kinetic has stronger B‐doped support, confirmed electrochemical impedance spectroscopy. provides valuable insights optimizing suspension preparation methods selecting appropriate boron concentrations nanodiamond composite electrodes applications.

Abstract Activated nanoporous carbons are widely used in various applications, where their efficiency is largely determined by specific surface area and pore structure. Traditional KOH‐assisted chemical activation methods primarily produce micropores, limiting the performance of these porous applications requiring a hierarchical arrangement micro, meso, macropores.
