Abstract
Nano-porous transition metal oxides, hydroxides and carbonate hydroxides based nanomaterial have received increased attention especially due to its electrochemical properties and potential applications and their wide application in many fields.
In this work, we focus our investigation on the synthesis of Ni and Ni/Zn based nanocomposites as mono and bi-phase nanoelectroactive materials based of α-Ni(OH)2. 2H2O and α*-Ni(OH)20,75H2O /Zn4(CO3)(OH)6.H2O, respectively, using a simple and low cost free template urea based hydrothermal process at 120 C growth temperature during 18 hours.
The morphological, textural and the structural selectivity of the as-prepared materials were characterized with different techniques such as: XRD, FTIR, FESEM, BET and Raman analysis in order to investigate their physico-chemical properties.
These obtained mono (Ni) and bi-phase (Ni/Zn) nanohybrids have shown the formation of heterostructures based of quasi-microsphere-like structure consisting of overlapping filaments and regular or irregular nanoflakes shape with two kind of pores with an important specific surface area around 97 m2/g and 34.64 m/g, pore volume around 0.38 cm3/g and 0.10 cm3/g and pore size around 12 nm and 14.86 nm, respectively.
Keywords: Nanohybrid, Nanocomposite, Hydroxide, Hydrothermal synthesis, Energy storage.
