Preparation method and application of foamed nickel/zinc oxide nano array photocatalytic material

The invention discloses a preparation method and application of a foamed nickel/zinc oxide nano array photocatalytic material, relates to the technical field of photocatalytic composite materials, and solves the technical problems of complex preparation process, high energy consumption, long time consumption and low production efficiency of an existing zinc oxide nano array. The preparation method comprises the following steps: immersing foamed nickel into a mixed solution of zinc nitrate Zn (NO3) 2.6 H2O and dimethylamine borane, carrying out a hydrothermal reaction to obtain a crude product, washing the crude product with deionized water and ethanol after the reaction is finished, and drying in a drying oven to obtain the foamed nickel/zinc oxide nano array photocatalytic material. The zinc oxide array is grown through one-step chemical bath, compared with a two-step method, the technological process is simplified, the preparation time is greatly shortened, in addition, nickel is low in cost, and the method
