Amination of various C3 alcohols such as 1,2-propanediol with ammonia was catalyzed by RhIn/C in water while Rh/C was totally inactive. Activated carbon FAC-10 was the best support in terms of activity and resistance to metal leaching. In the amination of 1,2-propanediol, RhIn/C produced amino alcohols in 68% total selectivity and 38% conversion. XRD and TEM measurements showed that RhIn alloy particle with size of 34 nm was formed on the carbon support.
