Three-dimensional and hierarchical porous materials enriched with 2D nanostructure can boost the electrochemical performance of carbon-based electrodes in the supercapacitor devices. These materials are obtained from novel precursors of palm oil stock biomass. The unique combination of hierarchical and 2D nanostructures was controlled using ZnCl₂ impregnation of 0.3–0.9 mol L⁻¹ with high-temperature pyrolysis.
