a GIXRD spectra of a nanowall film obtained from 0.1 M Zn(NO3)2ยท6H2O (with 0.1 M KCl). b Low-magnification TEM image of nanowall pieces and c high-resolution TEM image of a thin section of a nanowall piece. The inset of c shows the corresponding SAED pattern, depicting the single crystalline nature and the growth directions of the nanowalls
