Abstract

The invention discloses a method for producing hydrogen and hydrogen peroxide by hydrolysis. The method comprises the following steps: adding aluminum powder, nickel chloride and palladium chloride into a container, adding deionized water, and carrying out a hydrogen production and displacement reaction to obtain hydrogen and an aluminum-nickel-palladium ternary alloy; and adding deionized water and oxygen to the aluminum-nickel-palladium ternary alloy to carry out a hydrogen peroxide production reaction, and carrying out solid-liquid separation on the obtained solution after the reaction in order to obtain a liquid that is a hydrogen peroxide solution. The battery corrosion principle, the good hydrogen evolution performance of metallic nickel and the catalytic effect of palladium on the process of oxidizing hydrogen to produce hydrogen peroxide are used to improve the hydrogen and hydrogen peroxide production efficiency, and nickel salts and copper salts in reactants are converted into magnetic nickel-copper alloy which is recovered, so obvious economic and environmental benefits are obtained, thereby the method of the invention has the advantages of simplicity in operation, highefficiency in preparation, environmental friendliness, and suitableness for industrial large-scale production.

Description

technical field [0001] The invention belongs to the technical field of hydrogen production, and in particular relates to a method for producing hydrogen and hydrogen peroxide by hydrolysis. Background technique [0002] Hydrogen (H 2 ) as a renewable and environmentally friendly fuel, because of its high combustion value and good combustion performance, its application and promotion is a milestone in solving the current energy crisis. However, H 2 Due to its low density and explosive characteristics, it has the problem of inconvenient storage and transportation, which has always limited the use of H 2 further application. Compared to H 2 Gas and water are more convenient to transport and store. Therefore, splitting water to produce H as required 2 The technical factor can be H 2 The combination of production, storage and transportation has received more and more attention. [0003] Currently, the hydrolysis of H 2 The method includes the electrolysis of water to pro...
