TEM characterization of nanostructures commonly obtained at the growth temperature of 950°C. (a) TEM image of a tubelike nanostructure. (b) TEM image of a bamboo-like nanostructure with bowl-like joints. (c) TEM image of a bamboo-like nanowire with dumbell-like joints. (d) HRTEM image of tubelike nanostructure with the SAED as an inset. (e) HRTEM image of nanostructures with dumbell-like joints. (f) Enlarged view of the part marked with a white rectangle in (e). (g) Typical EDX analysis of nanowires. (h) Typical EDX analysis of a catalyst tip.
