Description
Technical Field
The invention belongs to the technical field of hydrogen energy, and particularly relates to a solid-state hydrolysis hydrogen production agent and a preparation method thereof.
Background
The hydrogen energy has the advantages of high combustion heat value, cleanness, no pollution, wide source and the like, and is ideal secondary energy for human beings in the future. The hydrogen energy system comprises the links of hydrogen preparation, storage and transportation, application and the like, wherein the preparation of the hydrogen with high efficiency and low cost is the premise of realizing the large-scale application of the hydrogen energy. The preparation method of the hydrogen comprises hydrogen production by water electrolysis, hydrogen production by fossil fuel, hydrogen production by chemical substance hydrolysis and the like. The hydrogen production by hydrolysis of chemical substances has the advantages of easy control of hydrogen production, high hydrogen purity and the like, can be directly applied to fuel cells, and is a novel hydrogen production technology.
Common solid-state hydrolysis hydrogen production agents include metals, ammonia borane, sodium borohydride, and the like. The metal hydrolysis hydrogen production agent, such as magnesium, aluminum, zinc, iron and the like, utilizes the reaction of metal and water to generate hydrogen, and is more suitable to be used as a material for preparing the hydrogen because the condition for generating the hydrogen by the magnesium and the aluminum is milder. However, the oxide film on the surface of magnesium and aluminum tends to inhibit the progress of the hydrolysis reaction [ Huang M, Ouyang L, Chen Z, et al, International Journal of Hydrogen Energy,2017,42(35):22305]. The ammonia borane aqueous solution can stably exist at normal temperature and normal pressure, and the hydrogen release of the ammonia borane can be promoted only by adding a catalyst. Ammonia borane has low requirement on catalyst, and metal particles with catalytic effect Can promote hydrolysis of ammonia borane, but only noble metals show excellent catalytic effect [ Can H, Metin ]
Applied Catalysis B:Environmental,2012,125:304]. The sodium borohydride hydrolysis hydrogen production efficiency is high, the hydrogen production quantity is large, the hydrogen purity is high, the safety is high, the environment is friendly, and the like, and the hydrogen can be rapidly released at room temperature under the action of the catalyst, so that the sodium borohydride hydrolysis hydrogen production catalyst is a popular material researched in recent years. For example, Soltani et al prepared bimetallic Ni-Co catalysts on activated carbon using a Co-precipitation method, which catalyzes NaBH at 30 ℃4The maximum hydrogen release rate of hydrolysis reaches 740.7 mL-min-1·g-1[Soltani M,Zabihi M,International Journal of Hydrogen Energy,2020,45(22):12331]. Although research into solid-state hydrolysis hydrogen production agents has been greatly advanced, there is some distance from large-scale commercial use.
