Multifunctional, Self-Activating Oxygen-Rich Holey Carbon Monolith Derived from Agarose Biopolymer

摘要: Agarose, a natural biopolymer, is carbonized to synthesize an economical lightweight (0.05 g cm–3) mesoporous carbon monolith with large BET surface area (625 m2 g–1). The prepared at different temperatures (700, 800, 900 °C) exhibits interesting morphologies without using any activating agent. holey pattern appearing °C, besides increasing the meso/microporosity, confirms self-activation higher temperature. Most interestingly, thick sheet-like morphology obtained 700 °C changed nanoporous flakes as synthesizing temperature increased 800 and °C. This synthesis approach affords oxygen-enriched meso/microporous that constitutes high pseudocapacitance in addition electric double layer charge. Lightweight excellent thermal mechanical characteristics having weight bearing capacity of ∼5900 times compared its developing deformity. electrochemical performance a...
