Changsha Research... of spherical Ni(OH)2 particles synthesized by the aqueous precipitation-crystallization method were investigated by SEM, TEM and XRD, and their growth mechanism was discussed. With the reaction beginning......
in the electrolyte. OH- ions existed in a non-free state, thus more Ni2+ ions became free in these electrolytes. As the polarization became more negative, Ni2+ ions were reduced preferentially; hence, the reduction... in the solution. Then, OH- ions became free by consuming H+ ions and reacted with Ni2+ to from Ni(OH)2 [27]. Figure 1(b) illustrates a favorable trend toward the side reaction with the increasing......
