a, b Cathodically (a) and anodically (b) deposited metal single atoms on Co(OH)2 nanosheets (denoted as C-M1/Co(OH)2 and A-M1/Co(OH)2, M = Ru, Rh, Pd, Ag, Pt, and Au). c, d Cathodically (c) and anodically (d) deposited Ir single atoms on different supports (denoted as C-Ir1/support and A-Ir1/support, support = MnO2, MoS2, Co0.8Fe0.2Se2, and N-C). The depositions were all conducted in a 1 M KOH electrolyte containing 100 μM metal precursors. For cathodic deposition, the deposition process was conducted in a potential range from 0.10 to −0.40 V for ten scanning cycles. For anodic deposition, the deposition process was conducted in a potential range from 1.10 to 1.80 V for three scanning cycles. The singly dispersed metal atoms are marked by yellow circles.
