Figure 4
SEM images of BN product fabricated by heating raw material system of amorphous boron, iron nitrate nonahydrate (Fe (NO3)3·9H2O) and urea (CO (NH2)2) at different temperatures. (a) Irregular particles at 1100°C. (b) Bamboo-like nanotubes at 1200°C. (c) Nanoflake-decorated BN nanotubes at 1300°C. (d)-(f) TEM images revealed the coexistence of bamboo-like and quasi-cylindrical nanotubes. (g) A low magnification TEM image of a nanoflake-decorated nanotube. The inset shows the high magnification TEM image. (h) A high-resolution TEM image of a part of nanoflake-decorated nanotube [37].
