Abstract

The invention provides an aluminum-containing composition for hydrolysis hydrogen production. The aluminum-containing composition is prepared by grinding, 60 wt%-95 wt% of Al, 0.5 wt%-10 wt% of Ga, 0.5 wt%-10 wt% of In, 0.5 wt%-10 wt% of Sn, 0.5 wt%-10 wt% of Bi and 0.5 wt%-10 wt% of Sr. The invention further provides a preparation method of the aluminum-containing composition for hydrolysis hydrogen production. All alloy components generate many defects in the grinding process, so that multiple intermetallic compounds including InSn4, InBi and In3Sn are formed among the components, dense oxide on the aluminum surface is destroyed due to existence of the defects and the intermetallic compounds, and then conduction of a hydrolysis hydrogen production reaction is promoted. According to the aluminum-containing composition, in the hydrolysis hydrogen production process, the hydrogen yield reaches 1,210 ml/g, and the hydrogen production rate reaches 97.2%.

Description

technical field [0001] The invention belongs to the technical field of hydrogen production materials, and in particular relates to an aluminum-containing composition for hydrogen production by hydrolysis, a preparation method and application thereof. Background technique [0002] Since entering the 21st century, energy issues have always attracted the attention of countries all over the world. The "National Medium- and Long-Term Science and Technology Development Plan" clearly states that: energy is an important field for my country's scientific and technological development in the next 15 years, and low-cost, large-scale development and utilization of clean energy is a key research field and a priority funding topic. At present, the world's energy composition is still dominated by the three traditional energy sources of coal, oil and natural gas. The depletion of the three traditional energy sources and the deteriorating environment have stimulated the development and appl...
