Abstract

The invention discloses an aluminum alloy for hydrogen production by hydrolysis. The aluminum alloy is prepared from the components in percentage by weight: 80%-94% of aluminum, 2%-5% of gallium and 3%-16% of indium and tin, wherein the sum of contents of the aluminum, the gallium, the indium and the tin is not less than 90%, and a metallic compound InSn4 is formed by at least part of the indium and tin. The invention further provides a method for improving an aluminum alloy hydrogen production rate. According to the aluminum alloy for the hydrogen production by the hydrolysis and the method for improving the aluminum alloy hydrogen production rate, the metallic compound InSn4 is formed in the alloy with a certain components, thus oxide films formed on Al crystalline grains are more advantageous to be destroyed, and the hydrogen production rate is obviously improved.

Description

technical field

[0001] The invention relates to the field of hydrogen production from aluminum alloys, in particular to a method for hydrolyzing aluminum alloys for hydrogen production and improving the hydrogen production rate of aluminum alloys. Background technique

[0002] Fossil energy is closely related to people's daily life and has played an irreplaceable role in the development of human society. Whether it is the gas used in people's daily life, or the electric energy and heat energy used in industrial production, most of them are provided by fossil energy. However, this kind of traditional energy is a one-off non-renewable energy, and its unsustainability and continuous huge human consumption have led to its output gradually shrinking. In addition, the massive consumption of fossil fuels has resulted in the emission of a large amount of greenhouse gases, causing the global temperature to rise and the sea level to rise, which intensifies the greenhouse effect. The...
