Abstract

The invention discloses a synthetic method of hydrogen. The method is that borohydride, hydroxide and water absorbent material are mixed evenly and then water is added to the mixture to form a borohydride gel solution, namely hydrogen storage material, a catalyst is added into the hydrogen storage material, and the borohydride is subjected to hydrolyzation to generate hydrogen. The method has the advantages that the hydrogen storage material provided through the method is stable in performance and convenient to store and carry, release rate of the hydrogen can be controlled, and the obtained hydrogen does not need to be filtered.

Description

technical field [0001] The invention belongs to the technical field of hydrogen fuel, and in particular relates to a synthesis process of hydrogen whose release rate can be controlled. Background technique [0002] Sodium borohydride is a commonly used complex hydride. Due to its excellent reducibility and wide range of uses, it has been widely used in industrial production in European and American markets, but its use in my country is still very small, and there is still room for expansion. [0003] U.S. Patent No. 6,358,488 has reported the process of using nickel, cobalt or hydrogen storage alloy powder to catalyze the hydrolysis of sodium borohydride to generate hydrogen. The reaction equation is as follows: [0004] NaBH 4 +2H 2 O→4H 2 +NaBO 2 [0005] This hydrogen supply process has the following advantages: [0006] (1) Sodium borohydride hydrogen storage fuel is an environmentally friendly substance, and the entire hydrogen generation and use process does not ...
