Abstract

Abstract: Green culms of Bambusa multiplex and the bamboo charcoal carbonized from the green culms at 700°C have been studied by means of X‐ray diffraction, X‐ray fluorescent element analysis, analytical scanning electron microscopy, and analytical scanning transmission electron microscopy (STEM), aiming at industrial applications as raw materials for functional devices and substances. It is revealed that the green culms and the charcoal contain a significant amount of Si, in particular, ∼18 wt % in the skin. The green culms comprise amorphous and crystalline celluloses. The charcoal has a so‐called amorphous structure which is composed of randomly distributed carbon nanotubes and fibers. The growth of Ag‐doped activated charcoal powders that were produced by two different methods using this charcoal powder has also been studied. Abstract : Chemical structures of green culms of Bambusa multiplex and its bamboo charcoal were identified. The charcoal has an amorphous structure with nanotubes and fibers. The growth of Ag‐doped activated charcoal powders has been revealed.
