Organophilic worm-like ruthenium nanoparticles catalysts by the modification of CTAB on montmorillonite supports

► Organophilic supported Ru catalysis was prepared. ► The CTAB intercalated montmorillonite was used as support. ► Worm-like Ru nanoparticles are distributed on the support. ► Catalyst was used in the hydrogenation of quinoline. ► It showed high activity and selectivity even without stirring.
