By controlling the conditions of homogeneous precipitation reactions, it is possible to obtain more and more complex structures from individualized nanoparticles to multi-scale micrometric particles. This is shown in the case of nickel and cobalt hydroxide. Precipitation using the combination of ammonia decomplexation and dodecylsulfate templating leads to nanostructured nickel hydroxide submicronic...
The aim of the present work is to determine at 60°C, the influence of the specific nature of nickel salt and pH on nickel hydroxide features such as crystallographic structure and morphology. Within the range 8≤pH≤11.5, a home-made nickel functionalized surfactant, nickel di-dodecylsulfate Ni(C 12 H 25 SO 4 ) 2 is compared to usual salts (nickel nitrate Ni(NO 3...
