Abstract
Magnetic Ag/Fe2O3 was prepared by the solvent thermal reduction method. The magnetic Ag/Fe2O3 was characterized by powder X-ray diffraction, scanning electron microscope and transmission electron microscopy, which suggested that the particle size was about 20 nm. The composite was used to synthesize benzaldehyde via the catalytic oxidation of benzyl alcohol by hydrogen peroxide. It was found that composite showed higher catalytic activity. The effects of reaction time, reaction temperature and the amount of silver in the catalyst on the reaction were investigated. The results showed that when benzyl alcohol and hydrogen peroxide was reacted for 12 h at 80 °C, silver content of 2 % mol in the catalyst, the yield of benzaldehyde was up to 61.3 %.
