Abstract

The invention discloses a TiFe hydrogen storage alloy containing Co and Y and a preparation method thereof. The chemical formula of the TiFe hydrogen storage alloy is TiFe0.86Mn0.1Co(0.1-x)Yx, wherein x is larger than or equal to 0.02 and smaller than or equal to 0.04. The novel TiFe0.86Mn0.1Co(0.1-x)Yx alloy is synthesized through a water-cooling copper crucible under the 99.9% high-purity argon environment. Through adding of Co and Y, the TiFe alloy is more easily activated and more easily absorbs hydrogen during first circulation. Meanwhile, the pressure of a hydrogen absorption and desorption platform of the alloy is low, and the slope of the hydrogen absorption and desorption platform is small. Under the temperature of 20 DEG C, the hydrogen storage quantity of the TiFe0.86Mn0.1Co0.06Y0.04 alloy reaches 1.95%(omega), and thus the TiFe0.86Mn0.1Co(0.1-x)Yx alloy is expected to provide efficient and practical hydrogen sources for equipment and production which take hydrogen as a raw material.

Description

technical field

[0001] The invention relates to a hydrogen storage alloy and a preparation method thereof, in particular to a TiFe hydrogen storage alloy and a preparation method thereof, which will be applied in the technical field of hydrogen storage materials. Background technique

[0002] With the further development of industrialization, carbon monoxide and carbon dioxide emissions have led to increased pollution and seriously affected the environment. China has ranked first in the world in terms of carbon dioxide emissions. To protect the environment from pollution and other dangerous pollutants, the move towards new energy sources is critical. Hydrogen is a potential candidate as a fuel source in various fields such as internal combustion engines and gas turbines. It has two advantages over other fuel systems:

[0003] 1. No pollution and environmental protection;

[0004] 2. Can be generated from other energy sources such as geothermal energy, solar energy and nuc...
