An aqueous solution of activated carbon and chloroplatinic acid is heated on a water bath for a few hours at 50°C, and after cooling, the solution is then made alkaline using sodium carbonate. The chloroplatinic acid is then reduced with hydrazine hydrate; however, this step is sometimes omitted in other preparations. After additional 2 hours of warming, the solution is filtered, washed with distilled water, and dried over calcium chloride to yield the catalyst. Platinum loading is typically b… WebThe reduction reaction of dissolved oxygen (DO) by hydrazine was investigated on activated carbon fiber (ACF) and Pt/ACF catalysts using a batch reactor with an external circulating loop. The ACF itself showed catalytic activity and this was further improved by supporting platinum on the ACF. While the reaction order of DO was obtained as 0.5 on both the ACF …
