抜粋

Local structure around Ni impurities in a carbon nanotube was studied by X-ray absorption fine structure (XAFS). The Ni was present in the form of Ni particles before the purification process. After the purification Ni content was decreased to a few hundreds ppm. The Ni K-edge XAFS could be measured by a 19 element solid-state detector. The Ni species was strongly bound to the carbon of the carbon nanotube with a Ni-C covalent bonds at 0.173 nm.
