On the photocatalysis evolution of heteroatom-doped Ag₄M₂ nanoclusters

Abstract

The structurally similar Ag4Ni2, Ag4Pd2 and Ag4Pt2 clusters exhibit a distinct activity evolution in photocatalytic reactions.

Recent progress in atomically precise metal nanoclusters for photocatalytic application

“…6(a)). 66 The overall structure is similar to a distorted hexahedron, in which four Ag atoms were at the midpoints of the four side edges and two foreign metal atoms were at the center of the top and bottom planes. Ag and M atoms formed an electron donor–acceptor pair, which was important for photocatalysis.…”

Programmable kernel structures of atomically precise metal nanoclusters for tailoring catalytic properties

“…103 Cheng and co-workers explored the catalytic performance of three metal-doped Ag clusters (Ag 4 M 2 (SR) 8 , M = Ni, Pd, Pt; SR = SPhMe 2 ; abbreviation as Ag 4 M 2 ) with a distorted hexahedron structure composed of eight sulfur atoms as vertices. [104] Four silver atoms are at the waist, and two heteroatoms are at the center of the top and bottom. The highest occupied molecular orbital and lowest unoccupied molecular orbital (LUMO) gaps of Ag 4 Ni 2 , Ag 4 Pd 2, and Ag 4 Pt 2 are 1.60, 2.24, and 2.61 eV, respectively, due to doping metal atoms.…”
