| 摘 要： | 对比研究两种不同载体ＭｏＯ３／ＳｉＯ２催化剂用于甲烷部分氧化反应，结果表明用醇盐法所制ＳｉＯ２做成的催化剂比用所买ＳｉＯ２做成的催化剂反应活性和选择性好；电镜（ＴＥＭ）结果表明前者是超细粒子催化剂，其平均粒径为１２．６５ｎｍ，粒度分布窄；ＢＥＴ及孔结构测定表明前者比表面积大，孔容及孔径小，孔径分布窄；ＴＰＲ结果表明前者ＭｏＯ３与ＳｉＯ２相互作用较弱。

| Abstract: | MoO 3/SiO 2 catalysts with two kinds of different supports for partial oxidation of methane to formaldehyde were studied.1MoO 3/ZSiO 2 catalyst prepared SiO 2 by sol gel (alkoxide) method had higher reaction activity and selectivity than 1MoO 3/QSiO 2 prepared by SiO 2 bought.TEM determination exhibited that 1MoO 3/ZSiO 2 was ultrafine particle catalyst.Its average particle diameter was 12.65 nm and it had a narrow distribution.BET analysis showed that 1MoO 3/ZSiO 2 had larger specific surface area and smaller pore volume.It had a narrow pore radius distribution.TPR results indicated that MoO 3 and SiO 2 had weaker interaction in 1MoO 3/ZSiO 2. |
