Controlled one-pot synthesis of RuCu nanocages and Cu@Ru nanocrystals for the regioselective hydrogenation of quinoline


bimetallics, one-pot synthesis, nanocages, core–shell nanocrystals, hydrogenation of quinoline


RuCu nanocages and core–shell Cu@Ru nanocrystals with ultrathin Ru shellswere first synthesized by a one-pot modified galvanic replacement reaction.The construction of bimetallic nanocrystals with fully exposed precious atomsand a high surface area effectively realizes the concept of high atom-efficiency.Compared with the monometallic Ru/C catalyst, both the RuCu nanocages andCu@Ru core–shell catalysts supported on commercial carbon show superiorcatalytic performance for the regioselective hydrogenation of quinoline toward1,2,3,4-tetrahydroquinoline. RuCu nanocages exhibit the highest activity,achieving up to 99.6% conversion of quinoline and 100% selectivity toward1,2,3,4-tetrahydroquinoline.
