In Situ Growth of Mg-Mof Derived Dendritic Carbon on Lignin Nanofibers for Efficient Capacitive Separation of Fluoride Ions

Published: Jan. 1, 2024

Fluoride contamination has become a global public health problem due to its adverse effects. The search for efficient and environmentally friendly fluoride removal technology is an urgent issue. Capacitive deionization (CDI) attracted much attention because of high efficiency, easy operation environmental friendliness. Electrode material crucial CDI systems. Herein, Mg-MOF-derived dendritic carbon materials (MMCNF) grown in situ on lignin nanofibers are successfully prepared by solvothermal synthesis. Thanks the specific surface area Mg-MOF structural stability nanofibers, MMCNF-3 capacitance 158 F·g-1 at current density 1 A·g-1. And retention 93.13% still maintained after 5000 charge/discharge cycles. In experiment simulated fluoridated wastewater, electrode reduces concentration ions 1.21 mg·L-1. It lower than safety standard 1.5 mg·L-1 set World Health Organization. This offers new technological options from wastewater.
