制备了负载型Au/TS-1催化剂,采用XRD、SEM、TEM等方法进行了表征,并将其应用于选择性催化氧化NO反应,考察了各工艺条件对NO催化氧化效率的影响.结果表明,Au/TS-1催化剂具有良好的结晶度,Au粒子成功地负载在TS-1上.该催化剂在选择性催化氧化NO反应中具有优异的低温催化氧化活性,在NO体积分数为1×10~(-3),O_2含量为10%,空速为5 000 h~(-1), Au的负载量为1.0%,180℃时,NO的氧化率高于55% (此时最适宜吸收处理);260℃时,氧化率可达到78%.

In this article, supported Au/TS-1 catalysts were prepared and characterized by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. Their performance in the catalytic oxidation of nitrogen monoxide (NO) was evaluated, and the effect of reaction conditions on NO conversion was examined. The results indicated that the Au granules can be successfully loaded on the molecular sieve TS-1 and the catalysts Au/TS-1 obtained exhibited good crystallinity. The catalysts Au/TS-1 also exhibit excellent performance in the s...
