【 摘 要 】

Nitrogen-doped porous carbon (NPC) materials were successfully synthesized via a Zn-containing metal-organic framework (Zn-MOF). The resulting NPC materials are characterized using various physicochemical techniques which indicated that the NPC materials obtained at different carbonization temperatures exhibited different properties. Pristine MOF morphology and pore size are retained after carbonization at particular temperatures (600 °C-NPC₆₀₀ and 800 °C-NPC₈₀₀). NPC₈₀₀ material shows an excellent surface area 1192 m²/g, total pore volume 0.92 cm³/g and displays a higher CO₂ uptake 4.71 mmol/g at 273 k and 1 bar. Furthermore, NPC₆₀₀ material displays good electrochemical sensing towards H₂O₂. Under optimized conditions, our sensor exhibited a wide linearity range between 100 µM and 10 mM with a detection limit of 27.5 µM.
