Description

technical field [0001] The invention relates to the field of energy technology. In particular, it relates to the composition and preparation method of an aluminum-based composite hydrogen-producing material for rapid hydrogen production. Background technique [0002] At present, environmental pollution is becoming more and more serious, and people's demand for energy is also increasing. However, the amount of non-renewable resources is limited. From the perspective of long-term interests, the problem we face is how to solve environmental problems and how to solve future energy problems. A large number of studies have shown that hydrogen is one of the most potential energy sources in the future [0003] To utilize hydrogen energy, the production of hydrogen is crucial. It is reported in the literature that 95% of the hydrogen currently used in the market comes from chemical hydrogen production, such as hydrogen production by reforming natural gas and coal gas, and its raw m...
