Fang, L. published the artcileNanoceria-promoted low Pd-Ni catalyst for the synthesis of secondary amines from aliphatic alcohols and ammonia, Synthetic Route of 111-87-5, the main research area is nanoceria palladium nickel catalyst secondary amine aliphatic alc ammonia.
This paper describes the preparation of bimetallic Pd-Ni catalysts supported over nanoceria with very low Ni and Pd loading (<0.5%) for the direct amination of aliphatic alcs. with NH3. Different metal impregnation methods were used for engineering the interaction between Pd, Ni and nanoceria. The as-prepared catalysts were characterized in detail by combining XRD, H2-TPR, H2-TPD, STEM-EDS-SDD and XPS. The sequence of impregnation of both metals and the Pd loading affected to an important extent the catalytic activity by conditioning the crystallite size and the Pd and Ni speciation, as well as the reducibility and reversible H2 storage properties. By optimizing the preparation protocols, a 0.5% Pd-0.5% Ni-Pd/CeO2 formulation prepared by sequential impregnation of the Ni and Pd precursors afforded 80% yield of dioctylamine at almost full conversion [TON = 1160 mmol per mmol (Ni + Pd)surface] in the direct amination reaction of 1-octanol with NH3 at 180° for 2 h. Metal leaching during the reaction could be completely avoided. The high catalytic performance of Pd-Ni induced by nanoceria places this catalyst among the best ever reported catalysts for the synthesis of secondary amines.
