A team of scientists from the Chinese Academy of Science (CAS) and Jilin University made the groundbreaking discovery of naturally occurring graphene on the Moon in 2024. The research, led by professors Wei Zhang and Meng Zou, along with colleagues from multiple key laboratories, analyzed lunar soil samples collected by China’s Chang’e-5 mission in 2020. Using advanced spectroscopic and microscopic techniques, the team identified graphene flakes two to seven layers thick embedded in a carbon-rich section of an olive-shaped sample measuring approximately 2.9 mm by 1.6 mm. This finding marks the first verification of natural few-layer graphene in lunar soil samples through microstructure and composition examination.

Graphene’s Extraordinary Properties

Composed of a single layer of carbon atoms arranged in a hexagonal lattice, graphene exhibits remarkable physical properties that make it a “wonder material” in materials science. Its exceptional characteristics include high electrical conductivity, extraordinary mechanical strength, and superior thermal conductivity. These unique attributes have led to extensive research into graphene’s potential applications across various fields, including electronics, energy storage, construction, and the development of supermaterials. The discovery of natural graphene on the Moon not only provides insights into lunar geology but also opens up possibilities for studying the material’s formation in extraterrestrial environments, potentially leading to new synthesis techniques for high-quality graphene on Earth.

Analysis of Lunar Soil Samples

The lunar soil sample analyzed by the research team was collected from a volcanic region on the Moon’s near side, approximately 2 billion years old. Using Raman spectroscopy and other advanced microscopy techniques, the scientists identified graphene flakes both as individual particles and as part of a carbon shell enclosing various elements, including sodium, magnesium, aluminum, silicon, calcium, tin, and iron. Notably, iron was only present in regions containing carbon, suggesting its role as a catalyst in the graphitization process. The structure of the graphene indicates formation through high-temperature processes, possibly resulting from volcanic eruptions or meteorite impacts, which may have allowed iron-bearing lunar soil to interact with carbon-containing gas molecules from solar winds.
