Copper nanostructures represent an important class of
materials
in CO2 electrocatalytic reduction (CO2ER) reactions,
but deciphering their molecular structures, especially those with
multiple and irregular organic–inorganic interfaces, remains
a grand challenge. Through comprehensive characterization of a 26-nuclei
copper nanocluster of [Cu26(DPPE)3(CF3CO2)8(CH3O)2(tBuCC)4H11]+ (DPPE is 1,2-bis(diphenylphosphino)ethane),
which is stabilized by quintuple ligand shells of phosphine, carboxylic
acid, alcohol, alkynyl, and hydride, we demonstrate in this work the
efficiency of hybrid ligands in controlling geometrical arrangements,
electronic structures, and catalytic performance of copper nanoclusters.
The diverse ligands in the cluster endow it with a peculiar geometric
structure and distinct electronic structure and, more importantly,
a delicate surface structure. As a result, the cluster displays high
performance in CO2ER to CO reaction.
An effective strategy is developed to synthesize a novel and stable layered Cu nanocluster in one pot reduction method. The cluster, with molecular formula of [Cu14(tBuS)3(PPh3)7H10]BF4 which has been unambiguously...
A novel alkynyl-stabilized silver-copper alloy nanocluster with the composition of [Ag13-xCu6+x(tBuC6H4C≡C)14(PPh3)6](SbF6)3 was prepared by (PPh3)2CuBH4-mediated reduction approach. The nanocluster featured a centred disordered-octahedral Ag7Cu6 kernel, which was protected by hybrid...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
