Tóm tắt

Titanium oxides nanotubes (TNTs) were prepared by hydrothermal method and used as nano-support for nickel nanoparticles. Indeed, nickel nanoparticles supported TNTs (Ni-TNTs) were in situ synthesized from nickel salt and TNTs by chemical reduction method using sodium borohydride (NaBH4) as reducing agent. The physio-chemical properties of Ni-TNTs nano-catalysts were fully characterized such as Transmission Electron Microscopy (TEM), Scanning Electron Microscope (SEM), and X-ray diffraction (XRD). The results showed that nickel salt was completely reduced to Ni0 metal with an average particle size of 12 nm. On the other hand, the catalytic activity is tested by the hydrodechlorination of chlorinated organic compounds. The hydrode-chlorinated conversion of 3-chlorophenol was obtained over 97%.
