a STEM image of the lattice fringes of the 2D PdSe2 reveals that the interplanar spacing along (002) direction is ~0.3 nm, scale bar: 5 nm. b Chemical structures and size dimension of EMIM cation and TFSI anion in the ion-gel. c EDXS element mapping of 2D PdSe2 reveals that the atomic ratio Pd:Se is close to 1:2, scale bar: 50 nm. d SAED pattern of the polycrystalline lattice structure of 2D PdSe2 film. e AFM image with height profile of the 2D PdSe2. f Room-temperature Raman spectra of the 2D PdSe2.
