Nano-Au/C catalysts for the selective oxidation of glyoxal into glyoxalic acid
Nano-Au/C catalysts were obtained by loading the gold nanoparticles which were prepared by photochemical reduction method to the activated carbon,and were used for the catalytic oxidation reaction of glyoxal into glyoxylic acid.The influence of temperature and pH on the catalytic activity,and the mechanism of Au/C catalyst on catalytic oxidation of glyoxal were discussed.The optimum conditions are:the amount ratio of Au:glyoxal is 1∶1000; The pH of solution can be controlled between 8.2 to 8.4 by using 1.00 mol/L NaOH solution under 45 ℃.
