Özet

In this study, a facile method is described for the Cu deposited Piperidine-4-carboxylic acid (Hpipe-4) coated magnetite (Fe3O4) nanoparticles. For which, Fe3O4 was used as magnetic core, Hpipe-4 as linker and active copper nanoparticles as the catalyst. For the reduction of Cu2+ to Cu-0 was accomplished by NaBH4. The phase and morphology of the as-prepared product is characterized by means of X-ray powder diffractometry, energy dispersive spectrometry, Scanning electron microscopy. Magnetic and catalytic properties of the product were followed by vibrating sample magnetometer and UV-Vis spectrophometer respectively. Experiments showed that the as-prepared Fe3O4@Hpipe-4@Cu nanocatalyst owned strong catalytic activity for the reduction of some aromatic nitro-compounds and organic azo dyes and also emphasizes the effect of copper nanoparticles on the degradation of rate of hazardous compounds by NaBH4. Fe3O4@Hpipe-4@Cu nanocatalyst show great promise for the treatment of industrial dye pollutants hence environmental protection.
