Description

technical field [0001] The invention relates to a material for hydrogen production by hydrolysis, in particular to an aluminum-based composite for hydrogen production by hydrolysis and a preparation method thereof. Background technique [0002] In modern industry, hydrogen energy is recognized as an ideal energy source for human beings in the future. Hydrogen has high volatility and high energy, and is an energy carrier and fuel. Hydrogen not only burns to release a lot of heat, but also the product of combustion is water, which does not pollute the environment. At the same time, the raw material for hydrogen production is unlimited water resources. In today's world, in order to solve the problems of energy shortage, increasingly serious environmental pollution and sustainable economic development, the development of clean new energy and renewable energy is imminent. Therefore, hydrogen energy, as a new energy source to solve the current difficulties faced by human beings, ...
