Abstract
The invention discloses a loaded multifunctional catalysis composite material, a preparation method thereof and an application of the composite material to catalytic removal of water pollutants. The preparation method includes the steps: preparing a zinc oxide nano-sheet loaded nickel foam (Ni@ZnO) composite material by an electro-deposition method; compounding molybdenum disulfide micro-nano particles on ZnO porous nano-sheets by an electro-deposition method to obtain Ni@ZnO/MoS2. The composite material Ni@ZnO/MoS2 combines the advantages of components such as nickel foam, the zinc oxide nano-sheets and molybdenum disulfide from the point of material performances, high catalytic degradation activity and recycled performances are achieved, photo-catalysis and electro-catalysis are combined from the point of material application, and the catalytic activity of the composite material is improved by the aid of synergistic effects of photo-catalysis and electro-catalysis.
