A sustainable approach for the manufacture of palladium (Pd) nanoparticles utilizing Morinda citrifolia leaf extract was established. The topological, crystallographic, and composition and structure of a UV–Vis spectrophotometer have been utilized to evaluate the generated nanoparticles, TEM, XRD, and FTIR investigations. The created nanoparticles underwent additional testing to see how well they removed the dyes rhodamine 6G (Rh-6 G), methyl orange, and Congo red. The generated Pd nanorods fully decolored nearly 99.9% of the Rh-6G dye in about 10 min. Greener fabrication for metallic nanoparticles has regularly been established, and cleaner and more effective nanorods for pollutant remediation have also been created. This study reveals the environmentally friendly synthesis of Pd NRs and its uses in environmental remediation.
