甲醇氧化制甲醛铁钼催化剂表面结构与活性OA北大核心CSCDCSTPCD
Surface structure and activity of iron molybdate catalyst for methanol oxidation to formaldehyde
利用共沉淀法在不同搅拌速度下制备了相同Mo / Fe原子比的甲醇氧化制甲醛催化剂，采用SEM、XRD和拉曼光谱等对催化剂进行表征，在固定床微反上评价催化剂活性和选择性。结果表明，搅拌速度增大，催化剂比表面积增大，催化活性增强，甲醛收率由600 r·min−1时的73.8%增加到10000 r·min−1时的95.7%（280℃）。此外，催化剂由片状的 MoO3和颗粒状的 Fe2(MoO4)3两部分组成，游离的片状 MoO3无明显…查看全部>>
Iron-molybdenum catalysts with the same atomic ratio of Mo/Fe for methanol oxidation to formaldehyde were prepared by co-precipitation method under varied rates of stirring. The catalysts were characterized by SEM, XRD and Raman spectrum and the catalytic activity and selectivity evaluated in a fixed-bed reactor.It showed that with an increase of stirring speed, the specific surface area of the catalysts increases and the catalytic activity enhances. The yie…查看全部>>
