摘要
通过对钒量的调控,合成了一系列HmPMo12-nVnO40杂多酸催化剂,并以H5PMo10V2O40为主体,SBA-16介孔分子筛为载体,采用浸渍法制备了负载型的HPMoV/SBA-16催化剂;利用SAXRD、WAXRD、FT-IR和UV-Vis光谱对合成的杂多酸样品及制备的负载型催化剂进行了表征结构和分析。结果表明:合成的H4PMo11V1O40,H5PMo10V2O40和H6PMo9V3O40样品均为Keggin型的杂多酸;且H5PMo10V2O40杂多酸能均匀地分散于SBA-16孔道中;制备的HPMoV/SBA-16催化剂较好的保持了SBA-16分子筛的三维立方介孔结构。
A series of HmPMo12-nVnO40 heteropolyacid catalysts were synthesized by the regulation of the vanadium content. And the HsPMo10 V2O40 catalyst was further supported on the SBA-16 mesoporous molecular sieves （HPMoV/SBA-16） with impregnation method. The SAXRD, WAXRD, FT-IR and UV-Vis spectra were used to characterize the structure of synthesized heteropolyacid samples and the HPMoV/ SBA-16 catalysts. The results showed that the synthesized H4PMo11 V1O40, H5PMol0 V2O40 and H6Pmo9 V3O40 samples were of Keggin-type heteropolyacid; the heteropolyacid H5PMol0 V2O40 could be evenly dispersed in the pores of SBA-16, and the prepared HPMoV/SBA-16 catalyst well maintained the 3D cubic mesoporous structure of SBA-16 silica molecular sieves.
