[Cu-Al-[Cu(C6H4O7)]2− hydrotalcite-like compound was firstly investigated as a potential electrode for the supercapacitors. [Cu-Al-[Cu(C6H4O7)]2− was achieved by hydrothermal method and Cu-Al-CuO-C was obtained after calcination. The electrochemical performances were characterized by an electrochemical analyzer system. The specific initial capacitance of the Cu-Al-CuO-C electrode is up to 88.44 F/g, and 69.54 F/g is retained after 1000 cycles of galvanostatic charge and discharge at 5 mA/cm2. It demonstrates Cu-Al-CuO-C hydrotalcite-like compound is a good candidate as electrode for supercapacitors. This work also offers a novel perspective to exploit the potential application of hydrotalcite-like family.

“…A lot of synthetic method have been introduced to synthesize NiO nanoparticles [10], such as sol-gel method [11], spray pyrolysis [12], sputtering [13], microemulsion method [14] and hydrothermal technique [15]. Different from the above synthesis techniques, the hot-injection method has some advantages such as simple process, less hazardous, relatively mild condition, low cost [16], and easily to produce high purity products. Moreover, it is excellent that the synthesized nanoparticles have good uniformity and monodispersity.…”
