Reduced core size causes the lattice of the core to decrease significantly, which changes how well it matches the lattice of the shell and, as a result, alters the lattice strains in the shell. Lattice mismatch between the metal core and the shell causes lattice strains in core-shell catalysts, which have a significant impact on the electronic structure of the metal shell and the overall activity of catalysts. ![]() The distinctive lattice stresses and ligand effects of core-shell catalysts, as opposed to alloy catalysts, can maximize the geometric and electrical properties.īecause the ligand effects and charge transfers between the components typically take place at the core-shell contact, the thickness of the shell has a substantial impact on bimetallic synergy. Their work was published in Nature Communications.ĭue to their bimetallic synergy, which varies with compositions and architectures, bimetallic catalysts are frequently used in many chemical synthesis processes. ![]() The team found that the catalysts’ activity increased with core size in the benzyl alcohol oxidation reaction. ![]() The conjugated dual size effect of core-shell bimetallic nanocatalysts was recently discovered by a team lead by Professor Lu Junling working with Professors Li Weixue and Wei Shiqiang.
