Fullerene hydrogen storage material modified by hydrogen storage alloy or metal nano-particle

Abstract

The hydrogen storing material is fullerene material with hydrogen storing metal or alloy compounded to the surface. Fullerene is spherical carbon molecule or carbon cage comprising several decades or several thousands of even number of carbon atoms and in the chemical expression of Cn, with n is 60 or other even number greater than 60. Fullerene as hydrogen storing material may be also mixture of tow or more spherical carbon molecule or carbon cage in any ratio. The hydrogen storing metals includes IA to IVB heat releasing soluble metals and VB to VIII heat absorbing soluble metals except Pd. The hydrogen storing alloy may be crystalline RE-Ni alloy in AB5 form, Zr-base or Ti-base Laves line AB2 form alloy, FeNi and Ti line AB form alloy, etc. The hydrogen storing material of the present invention has hydrogen storing capacity of 2.0-4.0 wt%.

Description

technical field

[0001] The invention relates to a fullerene hydrogen storage material modified by a hydrogen storage metal or a hydrogen storage alloy, in particular to a hydrogen storage material prepared by compounding a hydrogen storage metal or a hydrogen storage alloy with nanometer particle size on the surface of the fullerene. Background technique

[0002] With the gradual increase of fossil fuel consumption and depletion of reserves, and people's increasing emphasis on environmental protection, people are increasingly eager to use environmentally friendly and renewable energy. At present, people place the most hope on hydrogen energy. This is because hydrogen energy resources are very rich, which can be said to be "inexhaustible and inexhaustible"; the combustion product is only water, and water can be recycled; the fuel value is high, three times that of gasoline; Some internal combustion engines can use hydrogen as fuel with only a slight modification, or convert ...
