Study on Synthesis and Catalysis Application of Nano-Au/C Catalyst

Abstract:

The size controlled colloidal gold nanoparticles were prepared by sodium citrate photochemical system. The size and morphology of the gold nanoparticles were characterized by TEM and UV-Vis spectroscopy. nanoAu/C catalysts were obtained by loading the gold nanoparticles. The catalysts were used for the catalytic oxidation reaction of glyoxal and glucose in liquid phase. The research results showed that the catalysts had higher catalytic activity, and this preparation method is successful.
