Abstract

The present invention provides a nano composite hydrogen storage material. It is a mixture obtained by mixing 90 wt%-99 wt% of magnesium hydride and 1 wt%-10 wt% of nano carbon. Its preparation method includes the following steps: mixing nano carbon into magnesium hydride according to the required ratio, under the atmosphere of argon gas or hydrogen gas mechanically ball-grinding for 30 min-100 hr, then making desorption; or ball-grinding magnesium hydride for 1-100 hr, then adding nano carbon and ball-grinding for 30 min-10 hr, then making desorption. Its hydrogen storage capacity is 4.5 wt%-6.7 wt%.

Description

Technical field:

[0001] The invention relates to a hydrogen storage material, in particular to a novel hydrogen storage material containing magnesium and nano-carbon and having a synergistic hydrogen storage effect, and also relates to a preparation method of the novel hydrogen storage material. Background technique:

[0002] Environment, energy and sustainable development are the three major themes facing the world today, and hydrogen energy is one of the ideal clean energy sources. In recent years, the rapid development and commercialization of fuel cell vehicles has swept the whole world. Its high efficiency, energy saving, and good environmental performance of zero or near zero emissions make it a hot spot in the development of energy and transportation fields in the world today. However, the technical bottleneck in solving fuel cell vehicles is still the problem of hydrogen storage.

[0003] As we all know, among the various metal hydrides currently studied, Mg has att...
