| 摘要: 制备、表征了混合铝/铬金属氧化物柱撑α-磷酸锆(Al/Cr-ZrP),并对胶体化使用有机胺的种类、柱化液金属离子浓度以及金属离子用量等因素进行了研究。研究表明以乙醇胺为胶体化有机胺比使用正丙胺为胶体化有机胺所得到的产物的层间距更大;采用较低金属离子浓度、较高金属离子用量有利于Al/Cr-ZrP的合成。在Al/Cr比为1、以正丙胺为胶体化有机胺、金属离子浓度为0.067mol·L-1、金属离子用量为6.67CEC的条件下,制备出了混合金属氧化物柱撑α-磷酸锆,其层间距可达3.60nm, | |

| Abstract: The mixed metal oxides of aluminum and chromium pillared α-zirconium phosphate (α-ZrP) was prepared and characterized. The influences of the amine used in the colloidization of α-ZrP, and the concentration as well as the total amount of the cations of the intercalation solution on the properties of the pillared material have been inves-tigated. It was found that the pillared product with colloidized by ethanolamine had an interlayer distance higher than that colloidized by n-propylamine. The relatively low concentrations and comparatively large amount of cations benefit the increase of the interlayer distance of the product. The mixed metal oxides pillared α-zirconium phos-phate (Al/Cr-ZrP) showed an interlayer distance of 3.60nm and the BET surface area about 310m2·g-1. Such a large surface area is mainly contributed from the formation of the large amount of interlayer pores by pillaring. | |
