Enhanced Photocatalytic Activity of Pd-MWCNT/TiO2 Catalysts Synthesized by Ultrasound-Assisted Method and their Application for Hydrogen Evolution

摘要

Multi-walled carbon nanotubes (MWCNT) modified using TiO2 nanoparticles (MWCNT/TiO2) were prepared. Then, Pd-MWCNT/TiO2 catalysts were prepared by a ultrasound-assisted method for hydrogen evolution. The physico-chemical properties of the catalysts were characterized by TEM, XRD and EDX spectroscopy, respectively. The hydrogen evolutions were attributed to the Pd element and TiO2 nanoparticles attached on the surface of multi-walled carbon nanotubes, which act as reaction centers for H3 evolution.
