Structure, morphology and electrochemical performance of Zn-doped [Ni 4Al(OH) 10]OH
A layered double hydroxide [Ni 4Al(OH) 10]OH was doped with different amounts of Zn 2+ by coprecipitation and subsequent hydrothermal treatment. The structures of the samples were investigated by XRD, which showed that all are layered double hydroxides with very similar lattice parameters; and sampl...
