Comparative Study of Pd-Ni Bimetallic Catalysts Supported on UiO-66 and UiO-66-NH₂ in Selective 1,3-Butadiene Hydrogenation.

ABSTRACT: Selective hydrogenation of 1,3-butadiene (BD) is regarded as the most promising route for removing BD from butene streams. Bimetallic Pd-Ni catalysts with changed Pd/Ni molar ratios and monometallic Pd catalysts were synthesized using two differently structured metal-organic framework supports: UiO-66 and UiO-66-NH₂. The effects of the structure of support and the molar ratio of Pd/Ni on the catalytic property of selective BD hydrogenation were studied. The Pd-Ni bimetallic supported catalysts, PdNi/UiO-66 (1:1) and PdNi/UiO-66-NH₂ (1:1), exhibited fine catalytic property at low temperature. Compared with UiO-66, UiO-66-NH₂ with a certain number of alkaline sites could reduce the catalytic activity for the BD hydrogenation reaction. However, the alkaline en
