Green synthesis of Ag NPs on magnetic polyallylamine decorated g-C₃N₄ by Heracleum persicum extract: efficient catalyst for reduction of dyes.

ABSTRACT: Silver nanoparticles were immobilized on magnetic polyallylamine (PAA) decorated g-C₃N₄ by using Heracleum persicum extract as a biological reducing and stabilizing agent. The resulting nanocomposite, Fe₃O₄-g-C₃N₄-TCT-PAA-Ag, was then characterized using BET, VSM, XRD, TGA, FTIR, TEM, EDS and ICP. The catalytic performance of the synthesized nanocatalyst was considered in the reduction of rhodamine B, and methyl orange in the presence of sodium borohydride in the aqueous medium at room temperature. The results showed that Fe₃O₄-g-C₃N₄-TCT-PAA-Ag nanocomposite could promote both reduction reactions efficiently in very short reaction times (70-100 s). In addition, Fe₃O
