From: Iced photochemical reduction to synthesize atomically dispersed metals by suppressing nanocrystal growth

Fig. 1

Schematic illustration the iced-photochemical process. In a conventional photochemical reduction of H2PtCl6 aqueous solution, Pt nanocrystals are formed by the agglomeration and nucleation of Pt atoms (top row). Conversely, in the bottom row, we froze the H2PtCl6 solution before exposing it to UV irradiation and obtained Pt single atoms dispersed in ice. The ice lattice naturally confined the ions/atoms and prevented their nucleation. (scale bar, 2 nm)
