Carbonization and Preparation of Nitrogen-Doped Porous Carbon Materials from Zn-MOF and Its Applications

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-NPC and 800 °C-NPC ). NPC material shows an excellent surface area 1192 m /g, total pore volume 0.92 cm /g and displays a higher CO uptake 4.71 mmol/g at 273 k and 1 bar. Furthermore, NPC material displays good electrochemical sensing towards H O . Under optimized conditions, our sensor exhibited a wide linearity range between 100 µM and 10 mM with a detection limit of 27.5 µM.
