采用水热法成功制备CexSm1-xO2纳米棒,电镜照片显示其为长约10-20nm,宽约5nm的短棒结构且分散均匀。以CexSm1-xO2纳米棒为载体制备Au/CexSm1-xO2纳米棒用于CO催化氧化反应,发现少量Sm的引入,对其活性有明显的提升。
CexSm1-xO2 nanorods were successfully prepared by hydrothermal method. Electron microscopy showed that they were short rods with a length of about 10-20nm and a width of about 5nm. The Au / CexSm1-xO2 nanorods prepared by CexSm1-xO2 nanorods were used for the catalytic oxidation of CO. It was found that the introduction of a small amount of Sm had a significant improvement on the activity.
