Figure 2

(a) An SEM image of Ni(OH)2 nanoplates grown on oxidized MWNTs. Scale bar, 200 nm. (b) X-ray diffraction spectrum of a packed thick film of Ni(OH)2/MWNT. (c) TEM image of Ni(OH)2 nanoplates grown on oxidized MWNTs. Scale bar, is 100 nm. (d) A high-resolution TEM image of a Ni(OH)2 nanoplate attached to MWNTs. Scale bar, 5 nm. (e) XANES spectra of the Ni(OH)2/MWNT hybrid and the MWNT control sample at carbon K-edge. The blue dashed lines mark the carboxyl π* absorption at 288.5 eV and the carbonate π* absorption at 290.3 eV. (f) XANES spectra of the Ni(OH)2/MWNT hybrid and the Ni(OH)2 control sample at nickel L-edge. The inset shows XANES spectra at oxygen K-edge.
