以不锈钢为载体，采用阳极氧化法制备了0.01%Pt-0.02%Pd/不锈钢催化剂。当催化剂在1000 ℃煅烧时，在制备的催化剂上朝向甲苯的总氧化温度达到210 ℃。结果表明，在载体制备过程中，阳极氧化工艺的设计对提高催化剂活性是十分有效的。特别是，不锈钢载体已被证明可以有效防止催化剂在高温煅烧后失活。此外，还对催化剂的稳定性进行了考察. (c)2007 Elsevier B. V.保留所有权利。
A novel 0.01%Pt-0.02%Pd/stainless steel catalyst was prepared by using stainless steel as support and pretreatment via an anodic oxidation process. The total oxidation temperature over the prepared catalyst toward toluene was achieved at 210 degrees C as the catalyst was calcined at 1000 degrees C. The results indicate that the design of anodic oxidation process in the support preparation was quite effective in increase of catalytic activity. In special, the stainless steel support has proven to be effective for preventing the catalyst deactivation after high temperature calcination. In addition, the stability test on the catalyst was also investigated. (c) 2007 Elsevier B.V. All rights reserved.
