| 摘 要： | 通过水热法合成具有一维纳米结构的MoO_3纳米棒,利用MoO_3纳米棒的尺寸约束作用,以MoO_3纳米棒和铁盐为原料,采用浸渍法及高温焙烧下发生的固相反应,在经典Kirkendall效应影响下合成Fe_2(MoO_4)_3/MoO_3纳米棒催化剂。以空气氧化甲醇制甲醛为目标反应,评价其催化性能。结果表明,以Mo与Fe原子比2.2∶1制备的Fe_2(MoO_4)_3/MoO_3纳米棒催化剂催化性能较佳,甲醇转化率≥99.5%,甲醛选择性≥96.0%。

| Abstract: | MoO3 nano-rods with one-dimensional nanostructure were synthesized by using hydrothermal method.Taking the advantage of the dimension constraint of MoO3 nano-rods,Fe2(MoO4)3/MoO3 nano-rod catalysts were prepared by using the incipient wetness method and then being calcined via the solid-state reaction between MoO3 nano-rods and Fe salt in air at high temperature under the influence of classical Kirkendall effect.The catalytic performance of Fe2(MoO4)3/MoO3 nano-rod catalysts was evaluated by using methanol oxidation to formaldehyde as the target reaction.The results showed that Fe2(MoO4)3/MoO3 nano-rod catalysts with Mo/Fe atomic ratio of 2.2∶1 exhibited the better catalytic performance,methanol convension≥99.5% and the selectivity to formaldehyde≥96.0% were attained. |
