Catalytic Oxidation of 1,2-Propanediol over Bimetallic Cu@Au Core/Shell Nanoparticles

Ag-Based Catalysts in Heterogeneous Selective Oxidation of Alcohols: A Review

“…[98,99]). Various catalytic systems were proposed for partial oxidation of PG, including bimetallic NPs on the basis of Au and Pt subgroup metals [100,101], oxide Fe-Mo catalysts [102], supported FePO 4 /SiO 2 catalysts [103], etc.…”

Oxidative esterification of 1,2-propanediol to methyl lactate over Cu modified Au/γ-Al2O3 catalysts in an alkali-free system

“…The supported Au-Pd catalyst 17,21,22 (entries 2-4, Table S1, ESI †) and Au-Pt catalyst 16,23 (entries 5 and 6, Table S1, ESI †) were found to have high activity in the oxidation of 1,2propanediol to lactic acid. To further reduce the cost of catalysts, researchers have tried to modify precious metal catalysts with non-precious metals to increase the catalytic activity and reduce the amount of precious metals used 15,[24][25][26] (entries 7-10, Table S1, ESI †). Tian et al 15 prepared Cu-Au/Mg-Al hydrotalcite (HT) catalysts for the catalytic oxidation of 1,2propanediol to lactic acid.…”

Growth pathways of exotic Cu@Au core@shell structures: the key role of misfit strain

“…This makes the synthesis of the CuAu core@shell nanoparticles quite complex and needs a reliable strategy. Recently, CuAu core@shell nanoparticles have been successfully produced both in wet-chemistry synthesis [15][16][17][18][19] and in gas phase growth exper-iments by cluster beam technique 20,21 . For example, in the study carried out by Wang et al, the Au@Cu nanorods with high shape anisotropy were successfully produced using seedmediated method through localized epitaxial mechanism of Cu shells on a single-crystalline Au seed 12 .…”
