Problems solved by technology

However, the disadvantage of current hydrogen storage alloys is that alloys with high hydrogen storage capacity, such as magnesium-based alloys, have poor hydrogen absorption and desorption power, and the operating temperature of hydrogen desorption is still too high (magnesium-based alloys generally need to be above 300°C to desorb hydrogen), which greatly reduces the hydrogen storage capacity.

Embodiment 1

[0027] α-Al 2 o 3 The powder is subjected to sensitization processing (Sensitization Processing). The deployment of the solution of the sensitizer is to take 0.4g of SnCl 2 Dissolve in 34ml of deionized water, at this time SnCl 2 Will be hydrolyzed to produce Sn(OH 2)Cl white precipitate, then drop into 3ml of 1N HCl aqueous solution until the whole solution is clear and ready to use. Then 2g of α-Al 2 o 3 The powder (Da Ming Co., Ltd., TM-DAR) was immersed in the prepared sensitizer solution, and stirred at room temperature for 5 minutes to make the Sn 2+ Ions adsorbed on α-Al 2 o 3 On the surface of the powder, the filtrate is removed by centrifugation to obtain sensitized α-Al 2 o 3 Powder. The sensitized α-Al 2 o 3 The powder is immersed in 30mL of 0.9N NaOH (l) , 35mL of 2N NH 4 Oh (l) and 30mL of 0.3N AgNO 3(l) Formed silver ammonia solution, and added containing C 6 h 12 o 6 reducing agent solution. At this time, the Sn on the powder surface 2+ The...

[0030] α-Al 2 o 3 The powder is sensitized. The deployment of the sensitizer solution is to take 5g of SnCl 2 Dissolve in 7.5 mL of 37% HCl (l) , and then dilute the whole solution with deionized water to 50mL before use. Then 2g of α-Al 2 o 3 The powder (Da Ming Co., Ltd., TM-DAR) was immersed in the prepared sensitizer solution, and stirred at room temperature for 5 minutes to make the Sn 2+ Ions adsorbed on α-Al 2 o 3 On the surface of the powder, the filtrate is removed by centrifugation to obtain sensitized α-Al 2 o 3 Powder. The sensitized α-Al 2 o 3 The powder is immersed in 45mL of palladium chloride aqueous solution, and the preparation of the solution is to take 1g of PdCl 2 Dissolve in 30ml of 37% HCl (l) , and then dilute the whole solution with deionized water to 100mL before use. At this time, the Sn on the powder surface 2+ ions will reduce palladium ions and adsorb on α-Al 2 o 3 After the surface of the powder is reacted for 5 minutes, the pow...

Description

technical field [0001] The present invention relates to a hydrogen storage composite material and a method for forming the same. Background technique [0002] Hydrogen energy is a clean energy choice, and one of its key technologies is the safe and low-cost storage and delivery of hydrogen. Due to the problems of low hydrogen storage density, poor safety, energy consumption, and high cost in cylinder high-pressure hydrogen storage and liquid hydrogen storage and transportation, the most potential hydrogen storage method is to store hydrogen in metal or alloy materials. The principle of the hydrogen storage alloy is to use the temperature and / or pressure change of the external environment to make the alloy absorb hydrogen and form an alloy hydride. When the hydrogen needs to be utilized, the hydrogen is released from the alloy hydride. The process of hydrogen storage and release, such as diffusion, phase change, and chemical combination, is limited by thermal effects and sp...
