Abstract
In this study, a magnetic chitosan biosupport was synthesized and functionalized with a NNN pincer ligand to facilitate palladium immobilization. FT-IR, FE-SEM, EDX, XRD, VSM, ICP, BET, and TGA analyses were used to characterize the synthesized nanocomposite (Fe3O4@[email protected]). Then, its catalytic activity in the reduction of a wide variety of nitroaromatic compounds at room temperature was investigated using sodium borohydride as a reducing agent, as well as the degradation of three hazardous dyes, including Methylene Blue (MB), Methyl Orange (MO), and Rhodamine B (RhB). This technique is feasible due to its ease of purification, environmental friendliness, and high yield of product generation in a relatively short response time. The nanocatalyst is easily separated, recovered, and reused for numerous cycles without significantly degrading catalytic activity.
