From: Operando elucidation of hydrogen production mechanisms on sub-nanometric high-entropy metallenes
a The structural evolution from monometal catalysts to HEAs and from SACs to HESACs. b–d Low-resolution HAADF-STEM image (b), HRTEM image (c), and aberration-corrected HRSTEM image at the edge of a wrinkle (d) of PdRhMoFeMn HEMs. The inset in d is the AFM image of PdRhMoFeMn HEMs. e, f XRD (e) and SEM-EDS (f) results of PdRhMoFeMn HEMs. g Aberration-corrected HRSTEM and geometric phase analysis (GPA) images of PdRhMoFeMn HEMs and Pd metallenes. h, i aberration-corrected HRSTEM (h) and EDS elemental mapping images (i) of PdRhMoFeMn HEMs.
