SBA-15介孔分子筛负载金属酞菁催化氧化甲醛

采用浸渍法将钴或铁酞菁组装进有序介孔材料SBA-15中,通过XRD和N₂吸附方法对组装体进行了表征,研究了常温常压下,该组装体催化氧化甲醛的活性.结果表明,组装体具有优良的处理甲醛性能.钴酞菁比铁酞菁组装体的催化氧化活性高;钴和铁酞菁的协同作用使组装体具有更强的催化氧化活性,当二者摩尔比为1:1时,催化氧化活性最高;并借鉴金属酞菁处理有机巯醇的原理探讨了金属酞菁催化氧化甲醛的原理.

Catalyzed oxidation of formaldehyde by SBA-15 mesoporous molecular sieves supported metal-phthalocyanine

Cobalt-phthalocyanine or iron-phthalocyanine encapsulated into ordered mesoporous Silica SBA-15 adopting impregnation technique; the composites characterized through XRD and N2 adsorption techniques, the catalytic oxidation activity of formaldehyde in these composites was studied at normal temperature and atmospheric pressure. These composites possessed excellent catalytic properties for treating formaldehyde. The catalytic oxidtation activity of cobalt-phthalocyanine was higher than that of iron-phthalocyanine; the coordinated action of cobalt and iron- phthlocyanine maked the composite possessing stronger catalytic oxidation activity, when these two compostes was 1:1, the catalic oxidation activity was the lightest; and the principle of metal-phthalocyanine catalytic oxidation was inquired intousing the principle of metal-phthalocyanine treating organic mercaption.
