| 英文摘要 | ft-ir emission spectroscopy has been used to study the surface structure v2o5/tio2 catalyst with v2o5 loadings of 0.4%, 2% and 10% wt. prepared by of tio2 in nh4vo3 solution. the ir emission spectra were recorded insitu the course of a calcination of the impregnated catalyst from 100 degrees c to 500 degrees c. ammonium vanadate supported on tio2 was found to be decomposition more easily pure nh4vo3 most possibly owing to the chemical interaction between vanadate 1102. for 10% wt. v2o5/tio2 catalyst the ir peaks due to v2o5 phase appeared catalyst was calcined at 200-400 degrees c. when the catalyst was calcined at 500 degrees c of v2o5 phase were evidently reduced indicating that the part of v2o5 phase spreaded into highly dispersed vanadium oxide on tio2. for the catalysts with - loading of vanadium,the ir peaks due to v2o5 phase decreased and a broad peak from 1050cm(-1) to 900cm(-1) became prominent especially after a calcination at 500 the broad peak was tentatively assigned to the highly dispersed vox species which - be the two-dimensional vanadium oxide. this study also demonstrated that ft-ir spectroscopy is a very sensitive technique for investigating the surface structure oxide catalyst. |
