文摘

Highly uniform three-dimensional ¦Á-Ni(OH)₂ hierarchical architectures based on nanoslices were successfully synthesized on a large scale in a water-in-oil microemulsion of cetyltrimethylammonium bromide (CTAB)/water/cyclohexane/glycerol with Ni(HCOO)₂¡¤2H₂O served as both a nickel source and a weak alkaline source. The phase formation of ¦Á-Ni(OH)₂ takes advantage of the hydrolyzation of HCOO^? in Ni(HCOO)₂¡¤2H₂O precursor. The size and morphology of ¦Á-Ni(OH)₂ can be tuned through varying the experimental parameters. As-obtained 3D ¦Á-Ni(OH)₂ possesses high electrochemical sensitivity to H₂O₂, and the microstructures had a noticeable influence on their sensitivities, which indicate potential applications in the field of electrochemical sensing devices.
