Description
technical field [0001] The invention relates to the field of electrolyzing water to prepare hydrogen catalysis and hydrogen storage materials, in particular to a method for preparing a porous micron tube structure catalytic hydrogen storage synergistic effect material. Background technique [0002] With the development of economy and society, non-renewable energy such as petroleum and coal can no longer meet the needs of human beings. Hydrogen has a high combustion calorific value, and the combustion products are non-polluting and recyclable, so it is the most potential new energy source. [0003] The key to realizing large-scale and widespread application of hydrogen energy lies in the research and development of cheap and efficient hydrogen production technology and safe and efficient hydrogen storage technology. The industrial production of hydrogen through electrolysis of water is an effective means to obtain clean and sustainable energy hydrogen fuel on a large scale. ...
