Fig. 2: Fabrication and characterization of dense EER ATO-supported Ir catalyst (Ir/D-ATO).

a Schematic illustration of Ir/D-ATO for OER. b Fabrication process of Ir/D-ATO using solvent-assisted nanotransfer printing (S-nTP) with sequential e-beam deposition and high-temperature annealing. c TEM image with 50 nm scale bar (the inset images: SEM image with 500 nm scale bar (upper left) and SAED pattern (lower right) of Ir-/D-ATO) and d HRTEM image with 5 nm scale bar of the fabricated Ir/D-ATO. e XRD spectra of Ir/D-ATO before and after high-temperature annealing. f XPS spectra of the Ir 4f level on Ir/D-ATO. Note that a. u. represents arbitrary units.
