Tuning chemical compositions of bimetallic AuPd catalysts for selective catalytic hydrogenation of halogenated quinolines

Au_1−xPd_x bimetallic catalysts with low Pd entities on CeO₂ nanorods delivered high activity and chemoselectivity for hydrogenation of halogenated quinolines. Improved chemoselectivity could be attributed to the selective adsorption configurations of halogenated quinolines on Au via tilted orientation rather than on Pd via flat orientation.
