(A-a,A-b–A-e,A-f–A-g,B-a–B-c,B-d–B-e,B-f–B-g) low and high magnification HAADF-STEM micrographs of C-NT or g-C/Co3O4/3D PNi electrodes, (A-a,A-b–A-e,A-f–A-g) low magnification TEM views of C-NT/Co3O4 CP, g-C/Co3O4 LSs and C-NT/Co3O4 BCs/3D PNi respectively, (A-a- inserts) illustrating the exposed surface facets of non well-defined polyhedrons C-NT/Co3O4 CPs mesocrystals, (B-a–B-c,B-d–B-e,B-f–B-g) high resolution HAADF-STEM images show the corresponding atomic structure of the developed nanostructures recorded along the dominant {112} (B-c,B-e) and {001} (B-g) surface planes and {111/112} (B-a,B-b,B-d) and {110/001} (B-f) interfaces and (B-a,B-c,B-d,B-g)-inserts show the related electron diffraction patterns viewed down the {111}, {112}, {111} and {001} respectively.
