Magnesium-base hydrogen storage material having added transition metal oxide

Abstract

A Mg-base hydrogen-bearing material containing oxide of transition metal is prepared from pure Mg, powdered transition metal, and the oxide of transmition metal, such as Cr2O3, MnO2, Fe2O5, V2O5, TiO2, Fe3O4, NiO, MnO, or V2O3. Its advantages are high kinetic and thermodynamic performance of filling and releasing hydrogen, high hydrogen filling speed, and high hydrogen-bearing capacity.

Description

Technical field:

[0001] The invention proposes a material, specifically a magnesium-based hydrogen storage material in which a transition metal oxide is added to the magnesium-based hydrogen storage material. Background technique:

[0002] Hydrogen storage material is an extremely important functional material, which plays a very important role in the field of secondary energy. It is the basic material for fuel cells, rechargeable batteries. Due to the large thermal effect (62KJ / mol) in the hydrogen absorption and desorption process, it has a wide range of applications in thermal mercury, air conditioning, constant temperature, etc., especially for future electric vehicles, which cannot do without hydrogen storage materials. It is also a material with strategic value. As a component of fuel cells, it will be widely used in submarines, satellites, rockets, and aircraft power systems. The International Energy Agency (IEA) has determined that it will be a new type of hydrogen...
