a Synthesis routes to porous Rh/GDY electrodes. Optical images of b–e Rh/GDY electrodes with various bending morphologies. f Low- and g high-magnification SEM images of Rh/GDY. h Size distribution of Rh nanocrystals on the surface of GDY (403 Rh nanocrystals were counted). i-k EDS elemental mapping images of i overlapping, j Rh and k C elements on Rh/GDY.
