Figure 2From: Self-Assembled 3D Flower-Like Hierarchical β-Ni(OH)2Hollow Architectures and their In Situ Thermal Conversion to NiOa–d SEM images with different magnifications of the as-obtainedβ-Ni(OH)2samples. Inset ofa: the size distribution of the as-synthesized sample;e TEM image of one typical hierarchical hollow architectures;f HRTEM image taken from the age of the hexagonal phaseβ-Ni(OH)2sheets and the corresponding selected-area electron diffraction (SAED) pattern (lower left corner)Back to article page
