preparation example Construction

[0033]The preparation method of the multi-component alloy foam material developed by the present invention is mainly an electrodeposition method. As the basic framework for preparing foamed alloy electrodes, foamed plastics are the basis for ensuring the performance of electrodes. The foamed plastics with thickness (0.1-10mm), porosity (85%-99%) and pore diameter (0.1-22mm) were selected, and various roughening processes were studied on this basis. As the precursor foam material, one or a combination of open-cell organic materials such as polyurethane, plastic, polyether, and polystyrene can be selected as the precursor material of the multi-component alloy foam material.

[0034] The organic precursor material itself is not conductive, so a conductive layer needs to be applied. Before preparing the conductive layer, the organic solvent degreasing, chemical degreasing, hot water washing, strong etching, weak etching, ion washing and other processes are carried out. The way o...

Abstract

The invention discloses a multi-element alloy foam material and a preparation method thereof. The multi-element alloy foam material is a porous alloy material, and consists of two, three or more elements of metallic nickel, molybdenum, cobalt, zinc, ferrum, tungsten, copper and zirconium. In the preparation method, an organic foam material is used as a precursor; and the preparation method comprises the following steps of: performing conductive treatment on the organic foam material; electroplating the organic foam material which is subjected to conductive treatment; taking out the organic foam material from the electroplated organic foam material; and performing heat treatment to prepare the multi-element alloy foam material. The multi-element alloy foam material has a large specific surface area and high hydrogen-evolution catalytic activity, so the multi-element alloy foam material has multiple purposes in functional fields, such as electrolysis hydrogen production industry, battery industry and the like.

Description

technical field [0001] The invention relates to a multi-element alloy foam material and a preparation method thereof, in particular to the composition, morphology and preparation method of the multi-element alloy foam material. Background technique [0002] In traditional engineering materials, pores (macro or micro) are considered as a structural defect because they are often the core of crack formation and propagation, which adversely affects the physical and mechanical properties of the material. Based on this view, it is generally accepted that there should be no air holes, let alone large holes, in load-bearing members. However, a large number of natural porous substances composed of porous structural materials have existed in nature for thousands of years, such as honeycomb, cork, coral, animal bones, etc. This fact tells us that when the number of holes in the material (that is, the porosity) increases to a certain level, the material will have some exotic functions ...
