Abstract

The present invention discloses a preparation method of hydrogen storage of nano material containing magnesium erbium nickel, which employing cathodic electrodeposition: first preparing organic system solution with magnesium ion erbium ion and nickel ion, adding supporting electrolytes and using titanium matrix as working electrode, additional electric field proceeding electrodeposition to obtain magnesium contained hydrogen storage nano alloy materials. The preparation method of the invention works in mild condition, which can be proceed in normal temperature, the production process is simple and raw stuff used is cheap and economy with high-usage. The preparation method of the invention belongs to nonlinear process, being able to obtain coat uniform coating on matrix with complicated shapes by deposition, which possessing high exploitation value and market outlook.

Description

technical field [0001] The invention relates to the field of magnesium-containing hydrogen storage alloy materials, in particular to a preparation method of magnesium-erbium-nickel hydrogen storage nanomaterials. Background technique [0002] The application of hydrogen storage materials involves various fields. Hydrogen storage alloys not only have the advantages of safety and reliability, low energy consumption for hydrogen storage, and high hydrogen storage density per unit volume, but also have the function of purifying and compressing hydrogen gas. They are currently the most commonly used hydrogen storage materials. The currently developed metal hydrogen storage alloy materials can be roughly divided into rare earth series, magnesium series and titanium series, among which magnesium series hydrogen storage alloys are widely valued by countries all over the world. [0003] The first to study magnesium-based hydrogen storage materials was Brookhaven National Laboratory ...
