Ni–Cu/Al 2 O 3 catalysts for the selective hydrogenation of acetylene: a study on catalytic performance and reaction mechanism
Aiming at the preparation of metal catalysts with nanoscale structures, Ni–Cu/Al 2 O 3 nanoparticle catalysts ( i.e. , Ni&Cu-NP/γ-Al 2 O 3 ), containing a certain amount of Ni and Cu were prepared for the hydrogenation of acetylene. The highly dispersed and stable Ni&Cu-NP/γ-Al 2 O 3 catalys...
