Description

technical field [0001] The invention relates to a nano-device for preparing hydrogen, in particular to a hydrogen-producing nano-device, a preparation method thereof, and a hydrogen-producing method. Background technique [0002] Due to the increasingly serious problems of insufficient crude oil supply and environmental pollution in the world, hydrogen, as a kind of green energy, has the advantages of renewable, pollution-free, and high energy release during combustion, and has attracted widespread attention. At present, industrial hydrogen production mostly adopts the method of mineral combustion or electrolysis of water. The efficiency of these two methods of producing hydrogen is very high, but the method of burning minerals uses non-renewable energy, while the electrolysis of water requires a large amount of electricity, which limits their development, so there is an urgent need for a new high-efficiency, non-polluting And energy-saving method to produce hydrogen. Con...
