NOVELTY - Preparing self-propagating synthetic porous graphene involves using magnesium powder and other metal powders as raw materials, mixing magnesium powder and other metal powders in a molar ratio of 10:1-1:10 and mixing to obtain mixed powder, placing the obtained mixed powder in a crucible, and embedding the resistance wire in the mixed powder, and then placing the crucible in a closed container, passing carbon dioxide gas into the crucible, and controlling the flow rate of carbon dioxide gas to 20-500ml/minutes. The current of the DC power supply is adjusted to make the resistance wire heat, and the heated resistance wire is used to ignite the mixed powder in the crucible. The combustion reaction of the mixed powder is completed, added dilute acid solution to the resulting product to react, and the reaction time is 10-48 hours. USE - Method for preparing self-propagating synthetic porous graphene. ADVANTAGE - The method has high yield, product graphene impurity is little, with great specific surface area, in simple and cost-effective manner. DETAILED DESCRIPTION - Preparing self-propagating synthetic porous graphene involves using magnesium powder and other metal powders as raw materials, mixing magnesium powder and other metal powders in a molar ratio of 10:1-1:10 and mixing to obtain mixed powder, placing the obtained mixed powder in a crucible, and embedding the resistance wire in the mixed powder, and then placing the crucible in a closed container, passing carbon dioxide gas into the crucible, and controlling the flow rate of carbon dioxide gas to 20-500ml/minutes. The current of the DC power supply is adjusted to make the resistance wire heat, and the heated resistance wire is used to ignite the mixed powder in the crucible. The combustion reaction of the mixed powder is completed, added dilute acid solution to the resulting product to react, and the reaction time is 10-48 hours, and the oxide is removed through the reaction, filtered the reactant obtained to collect the precipitate, and the obtained precipitate is thoroughly washed, dried, and dried to obtain product.
