Preparation method and application of super-hydrophobic transition metal material/foam iron-nickel alloy structured catalyst

The invention belongs to the technical field of catalytic material preparation, and discloses a preparation method and application of a super-hydrophobic transition metal material/foam iron-nickel alloy structured catalyst. The method comprises the steps: (1) sequentially putting a foam iron-nickel alloy into an absolute ethyl alcohol solution, a hydrochloric acid solution and deionized water for ultrasonic cleaning; (2) dissolving a single metal salt or a mixed metal salt and hexamethylenetetramine in deionized water, and completely dissolving to obtain a hydrothermal reaction solution; (3) simultaneously transferring the foam iron-nickel alloy and the hydrothermal reaction solution into a hydrothermal kettle for reaction, cooling to room temperature after the reaction is finished, and taking out the foam iron-nickel alloy for drying; and (4) soaking the obtained foam iron-nickel alloy in a stearic acid ethanol solution, then taking out and drying. According to the method, the super-hydrophobic transition me
