| 中文摘要 | A series of silver-doped vanadium phosphorus oxides (Ag-VPO) catalysts were prepared by in situ syn-thesis, the catalytic tests showed that silver component significantly increased the overall activity for the oxidation of styrene bytert -butyl hydroperoxide (TBHP). It is interesting that Ag-VPO catalysts show no epoxidation selectivity but good selectivity for benzaldehyde in this study. To investigate the origin of the silver effect, the solids were characterized using X-ray diffraction (XRD), Fourier transformed-infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS) and other instruments, the (VO)2P2 O7, b-VOPO 4 , Ag(V2P2 O10) and Ag2 (VO2 )(PO4) phases were detected in all the Ag-VPO catalysts. This study also confirms that ratios of P/V play a crucial role in the activity and the selectivity of the catalyst, meanwhile,the other factors, such as solvent, oxidant concentration, reaction time, also have been investigated and reaction conditions are optimized. |
