Study on Preparation and Properties of Double Hydroxide Composite Nanomaterials

The purpose of this article is to synthesize a new type of visible light catalytic composite material NF@ZnO@ZnFe-LDH. In order to select a suitable LDH composed of metal ions, we selected Ni foam (NF) with a porous three-dimensional network structure as the carrier, and synthesized NF@MN-LDH composed of different metal ions by hydrothermal method (M is Divalent metal cations, N is trivalent metal cations), LDH nanosheets uniformly supported on the surface of nickel foam are obtained. Finally, the morphology characterization of the obtained object is studied. (paper)
