Investigation of using novel vic-dioxime metal complexes as precursors in deposition

Vic-dioxime derivative ligands and their Pd(II) and Cu(II) metal complexes were synthesized use as precursors in the deposition of metal nanoparticles. All ligands and their metal complexes were characterized via various analyses including FT-IR, 1H NMR, elemental analysis and magnetic susceptibility. The synthesized metal complexes were used as precursors in two different deposition methods; impregnation and deposition-precipitation, to prepare activated carbon supported metallic nanoparticles. The size and distribution of the synthesized nano-catalysts was analyzed by SEM/EDX and XRD. According to analysis results, the smaller and well dispersed nanoparticles were obtained by deposition-precipitation method. The Pd particles ranged from 2-20 nm and the Cu nanoparticles ranged from 20-30 nm. The catalytic activity of activated carbon supported nano-catalysts were performed in a hydrogenation reaction of styrene. Styrene/ethyl benzene ratio was determined with gas chromotography (GC).
