Here’s how you can make graphene dust using this method:
1. Prepare the sample: First, you will need to prepare a graphene sample. This can be done using mechanical means or chemical methods. The sample should have a thickness between 10-20 nanometers and should be clean and free from impurities.
2. Generate hydrogen gas: To generate hydrogen gas, you will need to use a gas generator. You can use an electric generator, a fuel cell, or a steam turbine.
3. Recrystallize the graphene: Once you have generated enough hydrogen gas, you will need to extract it from the air. To do this, you can use a vacuum chamber, which allows for the removal of the gas from the air.
4. Collect the graphene dust: After extracting the hydrogen gas, you will need to collect the graphene dust. This can be done using a filter that removes the remaining gases and solids from the sample.
5. Characterize the graphene dust: Finally, you will need to characterize the graphene dust to determine its properties. This can be done using various techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM).
