Palladium with interstitial carbon atoms as a catalyst for ultraselective hydrogenation in the liquid phase
Published 2011“…Catalytic properties of the final material were investigated in the hydrogenation of 3-hexyn-1-ol and 4-octyne to the corresponding alkene products and compared with a classical Lindlar type catalyst and other commercial Pd/C. It was found that the carbonised glucose Pd nanocatalyst with subsurface carbon substantially reduced undesirable isomerisations and over-hydrogenations. …”

Revisiting the Semi-Hydrogenation of Phenylacetylene to Styrene over Palladium-Lead Alloyed Catalysts on Precipitated Calcium Carbonate Supports
Published 2022-12-01“…With this philosophy in mind, we demonstrate in this work that alloyed palladium-lead (Pd-Pb) deposited on novel precipitated calcium carbonate (PCC) supports could be considered an upgraded version of the industrial Lindlar catalyst for the semi-hydrogenation of phenylacetylene to styrene. …”

Liquid-Phase Partial Hydrogenation of Phenylacetylene at Ambient Conditions Catalyzed by Pd-Fe-O Nanoparticles Supported on Silica
Published 2023-08-01“…The prepared catalysts consisted of mono- and bimetallic nanoparticles on an SiO<sub>2</sub> carrier and exhibited a selectivity as high as that of the commonly used Lindlar catalyst (which contains such hazardous components as lead and barium), while the activity of the Fe-Pd-O/SiO<sub>2</sub> catalyst was an order of magnitude higher. …”

Mediating trade-off between activity and selectivity in alkynes semi-hydrogenation via a hydrophilic polar layer
Published 2024-02-01“…By further enhancing the HPL through Mo doping, activated Pd1/MoWO3 achieves recorded performance of 98.4% selectivity and 10200 h−1 activity for semi-hydrogenation of 2-methyl-3-butyn-2-ol, 26-fold increase in activity of Lindlar catalyst. This observed vertical size effect of hydrogen spillover offers broad potential in catalytic performance regulation.…”
