NOVELTY - The preparation of assembled cubic nickel(II) hydroxide/graphene oxide composite material involves dispersing graphene oxide in water to obtain oxidized graphene mother liquid, diluting with deionized water to obtain graphene oxide dispersion liquid, adding nickel salt to dispersion liquid, and stirring until nickel salt is completely dissolved to obtain solution (A), dissolving topography inducer in dispersion liquid to obtain solution (B), dripping solution (B) into solution (A), and stirring to obtain precursor solution, hydrothermally reacting, cooling, and centrifuging. USE - Preparation method of assembled cubic nickel(II) hydroxide/graphene oxide composite material (claimed). ADVANTAGE - The method enables preparation of assembled cubic nickel(II) hydroxide/graphene oxide composite material by simple process. DETAILED DESCRIPTION - The preparation method of assembled cubic nickel(II) hydroxide/graphene oxide composite material involves (1) ultrasonically dispersing 0.1-0.5 g graphene oxide in 300 ml deionized water to obtain oxidized graphene mother liquid, diluting 60 ml graphene oxide mother liquid with 60-180 ml deionized water to obtain graphene oxide dispersion liquid, taking 60-90 ml graphene oxide dispersion liquid, continuously adding nickel salt after the precipitant is dissolved in the dispersion liquid, and stirring until the nickel salt is completely dissolved to obtain solution (A), taking 60-90 ml graphene dispersion liquid, and dissolving topography inducer in the dispersion liquid to obtain solution (B), where the topography inducing agent is cysteine, dripping the solution (B) into the solution (A) under stirring condition, and continuously stirring for 30-60 minutes to obtain precursor solution, and (2) adding the prepared precursor solution to a hydrothermal reactor at a certain filling ratio, hydrothermally reacting, naturally cooling, centrifuging the reaction product, centrifugal separating, washing and drying the obtained precipitate.
