Porous diamond materials with high surface area and self-sharpening capability have emerged as a frontier in diamond research. This study modified traditional metal-catalyzed etching techniques to construct interconnected porous structures on single-crystal diamond surfaces, featuring pore diameters (1-40 μm) and depths (50 μm), achieving a specific surface area of 82.63 m²/g. Raman spectroscopy and EDS analysis confirmed the preservation of diamond crystallinity and intrinsic properties during processing. The resultant porous boron-doped diamond (BDD) electrodes exhibited a remarkable specific capacitance of 58.65 mF/cm², representing a 63.4-fold enhancement over pristine electrodes. The assembled pouch-type supercapacitor demonstrated a record-high energy density of 38.64 Wh/kg among diamond-based devices, coupled with a specific capacitance of 93 mF/cm² and 92.7% capacitance retention over 10,000 cycles.
