C2H2 selective hydrogenation over the Pd and S-modified Pd catalysts: Unraveling the role of Pd active site spatial scale caused by S atom in adjusting catalytic performance

Synthetic Strategies of Supported Pd-Based Bimetallic Catalysts for Selective Semi-Hydrogenation of Acetylene: A Review and Perspectives

“…At present, there are four processes for the selective catalytic semi-hydrogenation of acetylene, namely gas-phase, liquid-phase, electrocatalytic, and photothermal [ 11 , 12 ] hydrogenation of acetylene [ 1 , 8 , 13 , 14 ]. Gas-phase catalytic hydrogenation has been the focus of scientists and industrial engineers because the vast majority of ethylene purification plants are using this strategy [ 15 , 16 ]. It is typically carried out in multi-bed adiabatic high-pressure reactors via two different scenarios depending on feed condition, namely front-end and tail-end configurations [ 17 , 18 , 19 ].…”

Atomistic Understanding of the Formation, Structure, and Decomposition of an Fe4C Iron Carbide Phase on a Copper Substrate

“…It was demonstrated that epitaxy between two metals may yield heterostructures with novel properties in terms of structure and reactivity. , For example, by epitaxial overgrowth of a second metal, ordered and unordered mixed alloy nanoparticles often with core–shell structure can be created . The lattice mismatch between the two metals plays a critically important role in the overgrowth process of these nanoparticles and metal layers, which also has to be considered when preparing, for example, metal carbides using the iron deposition method.…”
