Description

Technical field

[0001] The present invention relates to the technical field of carbon material production technology, in particular to a preparation method of graphene. Background technique

[0002] Energy is the cornerstone of human survival and development. At present, in the global energy system, the main energy humans rely on is still fossil energy (coal, petroleum, etc.). However, the large-scale use of these fossil energy sources will lead to the production of large quantities of greenhouse gases and hard-to-degrade polymer waste, which will have a difficult-to-recover impact on the environment. At the same time, the reserves of these energy sources on the earth are limited. From a long-term perspective, mankind is bound to face an energy crisis. Therefore, the task of seeking renewable energy that can replace petrochemical energy is urgent. Among all kinds of renewable energy, biomass is a unique and only renewable carbon source. It has the characteristics of renewable, ...
