英文摘要	A series of Zn-substituted Keggin phosphotungstic acid quaternary ammonium salt catalysts were prepared, and characterized by Fourier transform infrared (FTIR), X-ray diffraction (XRD). Their catalytic activities were evaluated by the oxidation of benzyl alcohol to benzaldehyde with H2O2 under solvent-free conditions. The effects of reaction parameters on the oxidation of benzyl alcohol were also investigated in detail. All the catalysts show good catalytic activity with fast reaction rate, eco-friendly and excellent selectivity for the desired products. In the absence of any solvent, the conversion of benzyl alcohol and the selectivity of benzaldehyde were found to be as high as 95.6% and 96.4% under optimum conditions in just 30 min. And a possible reaction mechanism of the oxidation of benzyl alcohol was deduced. ©, 2014, Science Press. All right reserved.
