In this work, we demonstrate a facile layer-by-layer (LBL) self-assembly method for controllable preparation of single-, double-, and triple-shelled NiO hollow nanospheres by calcining Ni(OH) sub(2)/C precursors formed at different stage. It is observed that the external nanoflakes of the NiO hollow...
