One-step co-precipitated beta-Ni(OH)(2) at different ratios of Ni/2-methylimidazole and its energy storage behaviour

In this study, a series of Ni-based Zeolitic Imidazolate Framework (ZIF) is successfully co-precipitated at room temperature with different ratios of nickel (II) nitrate hexahydrate (Ni(NO3)(2).6H(2)O) to 2-methylimidazole (mIM) at different ratios of 3:10, 1:1, and 10:3, denoted as Ni-ZIF-1, Ni-ZIF...
