specific Embodiment approach 1

[0029] Specific implementation mode one: combine figure 1 To illustrate this embodiment, a method for preparing a mobile hydrogen source in this embodiment includes the following preparation steps:

[0030] Step 1: Prepare Aluminum Plate 1:

[0031] Fix the metal aluminum plate 1 with a thickness of 0.1-30mm, scrub the upper surface of the aluminum plate 1 with an organic solvent to remove oil stains and expose a clean surface, and set aside;

[0032] Step 2: Metal gallium backup:

[0033] Take an appropriate amount of gallium metal and place it in a beaker, heat the beaker until the gallium metal melts into a liquid state, and set aside;

[0034] Step 3: Heating Aluminum Plate 1:

[0035] Pour the liquid gallium 2 in step 2 onto the upper surface of the aluminum plate 1 in step 1, and heat the area covered with the liquid gallium 2 from below the aluminum plate 1 to ensure that the metal gallium is always in a liquid state. At the same time, when the aluminum plate 1 is he...

specific Embodiment approach 2

[0044] Specific implementation mode two: combination figure 1 To illustrate this embodiment, the upper surface of the aluminum plate 1 in Step 1 of this embodiment is scrubbed with an acetone organic solvent. With such arrangement, the oil stain on the upper surface of the aluminum plate 1 can be effectively removed to prevent the oil stain from hindering the liquid gallium 2 from entering the aluminum plate 1 . Other compositions and connections are the same as in the first embodiment.

[0045] The organic solvent in this embodiment is absolute ethanol, and the oil stain on the upper surface of the aluminum plate 1 can also be removed by absolute ethanol.

specific Embodiment approach 3

[0046] Specific implementation mode three: combination figure 1 To illustrate this embodiment, in step 2 of this embodiment, 8ml-12ml of liquid gallium 2 is placed in a beaker, preferably 10ml. Such setting ensures that the liquid gallium 2 can completely cover the exposed fresh aluminum substrate after milling. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

[0047] Specific implementation mode four: combination figure 1 To describe this embodiment, the end of the ultrasonic tool head 3-1 of the ultrasonic vibration device 3 in Step 5 of this embodiment is pressed into the aluminum plate by 0.03mm-0.07mm, preferably 0.05mm. With such a setting, the ultrasonic vibration can be effectively transmitted to the aluminum plate without damaging the ultrasonic tool head, so that the density of the aluminum plate fluctuates with the change of sound pressure. Other compositions and connections are the same as those in Embodiment 1, 2 or 3. ...

Abstract

The invention discloses a method for preparing a mobile hydrogen source, which relates to a method for preparing a metal material. The invention aims to solve the problems of complex process, high cost, low production efficiency and potential safety hazards in transportation existing in the existing hydrogen production technology. Step 1 of the present invention: fix the metal aluminum plate, and scrub the surface of the aluminum plate with an organic solvent; Step 2: metal gallium for later use: take an appropriate amount of metal gallium and place it in a beaker, and heat the beaker until the metal gallium melts into a liquid state; Step 3: put The liquid gallium in step two is poured on the upper surface of the aluminum plate, and the area covered with liquid gallium is heated from below the aluminum plate; step four: remove the oxide film; step five: the ultrasonic vibration device is in close contact with the aluminum plate; step six: obtain aluminum Gallium alloy: Turn on the ultrasonic vibration device, so that the liquid gallium and the aluminum plate vibrate mechanically with the head of the ultrasonic tool, and the liquid gallium enters the aluminum plate to obtain an aluminum-gallium alloy with uniform structure; Step 7: Obtain hydrogen. The invention is used for hydrogen production.

Description

technical field [0001] The invention relates to a metal material and a preparation method thereof, in particular to a preparation method of a movable hydrogen source. Background technique [0002] With the depletion of mineral resources on the earth and the deterioration of the urban environment, people's demand for clean energy is becoming more and more urgent. Hydrogen is an ideal clean energy, but it is expensive to prepare, and there are difficulties in storage and transportation, so it has not been applied on a large scale. Traditional hydrogen production methods are mainly divided into hydrogen production from fossil fuels and hydrogen production from electrolyzed water. Among them, hydrogen production from fossil fuels has disadvantages such as backward technology, poor economic benefits, and serious pollution, and oil, natural gas, and coal are valuable primary energy sources. The energy problem has not been fundamentally solved; the main problem of hydrogen product...
