Synthesize of dendritic fibrous nano-silica functionalized by cysteine and its application as advanced adsorbent

l-Cysteine-modified dendritic fibrous nanosilica grafted by amine groups (Cys-DFNS-NH2) have been synthesized by a novel hydrothermal method. The N2 adsorption–desorption isotherms analysis on the Cys-DFNS-NH2 show that the average pore volume and surface area of the prepared fibrous Cys-DFNS-NH2 we...
